- Repair Scratched Motorcycle Windshield | How To Remove Scratches On A Bike Screen | Honda Fireblade Project | 004
In this Honda Fireblade episode, I restore an original screen and fit it to my CBR900RR project bike. I am building this bike to be a road-going runner, not a fully restored bike.
This is what I used
3M Headlight Restoration Kit: ebay.us/M9Hddb
I really do not like the black double bubble screen that the bike came with. I think it makes it look cheap. Ha, cheaper maybe! I always prefer clear or lightly tinted screens.
I managed to find an original screen on eBay, but it does have a few scratches and scrapes. This was reflected in the price :)
I intend to polish it to remove all of the blemishes. I am going to use a 3M headlight restoring kit. I have used these before on car headlights with amazing results so I thought I would try it on a motorcycle screen.
Obviously, the screen is bigger than a car headlight and has two sides so it will be a bigger job. There is the advantage though that the screen doesn’t have the greeny-yellow discolouration that headlights get so it should be easier.
After a lot of polishing, I got a really great result. The final finish is very acceptable. I would recommend doing this to anybody that has a scraped motorcycle screen, it makes the bike look really smart.

First he helps me with my 900rr valve adjustment, then shows me step by step how to restore my windscreen?? Brilliant mechanic with a brilliant channel. Looking forward to more videos in the future! My 94’ 900rr restoration is nearly completed thanks to you!
Great to hear! But you are being too kind :) Good luck with your restoration.
Looks a lot better. This has given me an idea for my old helmet visors. I’ll see if they maintain clarity afterwards.
Somewhere in the comments on this video, somebody has put that this doesn't work with visors. I can't remember why. Let us know how you go on if you try it.
I’m about refurbish a rear window on a Sunbeam Alpine hard top and came across this video. I appreciate the clarity of the explanation as well as the honesty as to how much work is involved. I know how difficult it is making and editing videos and think this was excellently made so new sub and liked for your troubles. Know Expert.
Thank you for your kind words. I am pleased that what we have done may help you. Good luck with your Alpine.
Or use a headlight restoration kit, the type that comes with the spray sealant. The sealant they supply is like magic. Sand/polish it first and then spray the sealant last as per instructions. The sealant makes it go incredibly clear(it fills the tiny swirls from sanding/polishing) and it's a UV protectant as well, stopping the sun damage happening again for years.
What kind of sand / polish would you recommend?
Sounds like an interesting kit I'll have to look that up. I see quite a few people sanding then clear coating headlights which sounds broadly similar. Probably harder to do than polishing though as getting perfect paint finishes is an art in itself. Cheers!
@@frfr2023frfr You want to go up in stages, up to like 3000 grit with sand paper. The kits come with the right stages of paper and doing it on a drill makes much lighter work of it. I linked a kit in the description which you can check out.
@@SPANNERRASH Tried it yesterday on my windshield. Worked up till 2000 and afterwards tried a polisher. Unfortunately it became very blurry. Any idea what to do?
@@frfr2023frfr If its blurry as though its "frosted", you need to do a lot more polishing. Are you using a fine grit compound on a foam pad like the kit?
It can take a bloody long time with the polish like I mentioned in the vid, but stick with it, and it will become clearer and clearer.
If its still got sanding marks in, you need to sand with a finer grit to get rid of those before polishing as the polish wont remove deeper sanding marks. Hope that helps!
Just what I was looking for. Have a windscreen that looks flawless in the day but You have to sit up and look over it at night due to years of aggressively cleaning off bug carcass. Gonna try this, thanks.
Haha I've scratched many a screen in the same way. Hope this technique works for you too.
I've just manage to source a cbr900 92 screen and this is a big help as I was looking I to getting the scratches out. just purchased the M3 kit 😉
I'll be like new, just be patient and put the time into the polishing.
Nice work. Not many people can achieve the steadiness & most of all the patients for that kind of results. I’ve been there and I can honestly say every time I say to myself, last time. Way to much work. Then again the results leave you coming back for more. 😅 Ride on brother!
Thanks George. It is a lot of work, but definatley worth it. I am painting now, that can be really satisfying, but also very frustrating!
Wow great videos.. giggled at the finished product…very good effort.
Thanks Spencer. Glad you're enjoying them. I was pretty pleased how this old screen came out considering! :)
Handy to find this video, I’m doing exactly the same screen👍
Awesome, I hope your screen comes up just as well as mine did. Take your time, it's not a quick process, but well worth it in the end! 😁
Thanks for this. I scuffed a windsheild when I was working on a bike and now have that to add to my fixes. At least I know what to expect. Lots and lots of polish!
Cheers Aaron, hope the guide helps you out with the scuff.
Great result well done. Looks good on the bike 👍
Cheers Alan, loving the OE look with the clear screen. I was really chuffed it polished up so well. Took bloody ages mind.
Awesome im going to actually try this on a bubble retro see thru chair!!!
Sounds like a cool project! Take your time and I bet you can get it to a perfect finish. Stick with it, hope it works out.
thank you very much sir
greetings from Yemen
u saved my life
You're most welcome! :)
That’s a sweet ride you’ve got there.
Thanks Cory, the CBR900RR Fireblade is a wonderful bike.
Very helpful video and interesting to hear the exact same accent that my family have. I was born here in Australia.
Cheers Mark, sounds like your folks did you a big favour back then 😂
Super helpful! Thanks so much, looks great!
Glad it was helpful!
I know its been a year since this video was uploaded. But, thank you kind sir for this tutorial 😊
Glad it was helpful, and thanks for letting me know you enjoyed it.
I like your honesty keep going 👍
Cheers Brahim 😁
awesome video! Very clear demonstration. Found this to be very useful with the scratches on my windshield.
Cheers, really glad it's helped you out :)
Very useful thanks ! I need to do this on my Glider canopy but have been very nervous to try !
I'm sure that if you are methodical it will work out well. Good luck.
We all have so many things that are plastic. Keeping them clear is always a pain. My prescription glasses are a form of plastic and now I never touch them unless under running water and then after they are wet under the water, I apply soap to clean them. Follow up with a soft wipe with a clean soft cloth. I used to use paper towels or anything to get the dust off before and the haze became so bad replacement was in order.
Thank you for the nice video.
Headlights go the same way. You have to be so careful.
Modern scratch resistant coatings are pretty good though
I really hope I can fix mine. Yours looks great!
Thanks Debra, if you take your time with the kit it works a treat. Good luck :)
i’ve done probably 12 headlights, 10 with the 3m products in that same kit. The 3m kit you used is excellent, i think it would have helped to spend a little more time at p3000 trizact wet sanding as if it were a pre-polishing. Once the plastic starts to clear out a bit more from the p3000 trizact then the polish step will be easier/faster. Nice project, it came out looking good!
Thanks for the advice. I will bear it in mind next time. Cheers.
Used a lot of this methodology (with thanks to OP), but found that using a heat gun produces faster and better results, followed by a hand polishing. I guess it depends on how DEEP the scratches are though.
Thanks for your comment. Interesting, I have used a heatgun to refresh coloured plastics, but didn't have any idea that it could improve scratches in clear. I will definitely be giving this a go.
Fantastic results, great video thank you for sharing
Thanks, I was really pleased with how it came out. Much better thatn the one I replaced.
@@SPANNERRASH absolutely, and you are right the clear screen looked so much better. Great work sir
I really miss the old trigger/speed lock buttons drills used to have 30 years ago. Pull the trigger to your desired speed, push in the trigger lock button and thats it... constant speed of your choice and no having to squeeze the trigger full time.
Happy day! :)
Get a hair tie
I agree, I think the 500 would be a bit harsh. I've watched a couple of vids, doing the same, on helmet visors. The did them by hand, using 800, 1000 & 2000 paper, and the results were very good.
Yes, finer grade grit, and a lot of time for the best results. I used this technique on my car headlights first.
Ya, but did you see those deep scratches? It would have taken you DAYS with 800!
Great job, I'm going do my screen now.
Hope it works out well for you Ray, its a great technique to revive a plastic screen.
Looks great. Nice job
Thank you! Cheers! It worked out really well.
Fireblade is ready for your IOM race.
It would be great, but I doubt I could make the 118mph average lap requirement for qualifying!! Although in '98 they did 120 average in the production class. Impressive bikes even then.
Superb job !😉👌
Thanks, I hope it has been of use to you.
"A" for effort, but if it ain't perfect it sucks!! Thank You, JD
Only 10 hours away from perfect :)
Great job 👍
Thanks Anthony!
Nice job 👍
Cheers Clifford, I was very pleased with how it came out. Well worth the time spent polishing in the end.
Dry interesting thank you for sharing.
Thanks for watching, glad you found it interesting.
The clear screen is definitely an improvement
Yes I love it.
Excellent!
Thank you! Cheers!
Great work! Sadly, the windshield may fade / yellow after a while. Use some polymer coating in order to protect it from UV rays. There are kits that come with 500ml of polymer and an electric cup to atomize it. I did my car headlights and motorcycle windshield with it and they're like new. The video is a year old now so I'm sure you've already looked into it :)
It seems to be holding up quite well. I have used some detailing spray, but some people have suggested ceramic coating.
I would have followed up with McGuires PlastX.
@@SPANNERRASH Plexus is another good plastic polish/protectant.
Are you just being modest or is it flawless? It looks flawless on video ...
Haha cheers! :D It came out very well, but nothing is ever perfect!
I found sanding kit through hot tub repair kit. My kit had several strips of fine too really fine work! Can't find fine enough sandpaper, look at hot tub repair kit!
Great tip Tim, thanks for sharing!
Clearly that was a smart choice starting out with 1500. Then finishing with 3000. Then polishing with compound that has probly 8000 grit. I think there is a gap inbetween and they should provide 5000-6000 grit pad. Thats why it takes so long with the polishing compound to get the haze out.
Sounds like a good idea, but you have to balance the cost against the effort that it takes. I was, and still am, very pleased with the result.
Cheers Dave, I think you're right about that, it would speed the job up a bit to stage it up. Works with some persistence though!
Thanks for the tune-up! I finally now know what grit he's starting with! JD
Amazing job .I have the same model of bike and screen is worse hope this fixes it .thanks for the video
Cheers Stewart, take your time with it and be methodical, and I'm sure you'll end up with a good result too. Hope the vid helps!
@@SPANNERRASH yes it's helped many thanks .just ordered the the same kit
When it cut to the bike I totally thought the tray was part of a super trick endurance tank. And then you started putting your hardware in it. Bahahaha.
Haha its much more humble than that :D Really handy magnetic tray though
Great video, very helpful. Many thanks. I have bought 3M and have tried this for the first time and followed the instructions to tea unfortunately the results I have gotten unsatisfactory and I’m very disappointed. I have tried to do this method and still have the same results. Shame.
Maybe you need a more powerful drill? Or maybe you are moving between the steps too quickly. It can take quite a time, but you really should be able to get a good result. I have done this on other screens and headlights a few times, sometimes using wet and dry, and paint polishing compound with a standard polishing mop before I got the 3m kit with good results. Good luck if you do give it another go.
If it looks 90% better than you should be happy you did not have to spend more $$$$$ to have it done by a professional or even purchase a new one. Great video , thanks, Peace.
I'm really pleased it worked out really well. And a year later it is still good. Thanks for the comment.
Excellent job, two more jobs I know how to do now, thanks to your video's keep up the good work and thanks
Cheers, glad they're helpful! :)
Stay blessed 🙌
🙌
Spray with H2go ceramic althogh PlastX has sime UV protection also...
Slow and steady...
Thanks for the recommendation 😃
Thanks for this video!!! amazing edit and vive!!!! New Suscribrer
Thanks for your feedback, I am glad you have found it useful.
I've found it helps to have some dish soap/fairy liquid in the water because it allows a smoother sand
Never thought to use it on this, but I always do when wet sanding paint work.
The very next thing you should have done to that windshield was to coat it with some type of UV protection sealant, spray or coating. It looks great now, but in a lot of sun, it will fade much quicker than when new.
That would be a good idea, but I wasn't sure what to use so didn't get around to it. but there isn't much chance of a lot of sun in the UK :)
excellent
Thanks for watching! I love a clear screen.
Turned out really good!! Nice job!!
Thanks mate, I'm well chuffed with the result.
Brilliant. I think a lighter polish to finish may help. But Id certainly be happy with that.
Actually looks great on the bike
@@jedigeekbiker Cheers! I was pretty pleased with the results considering what I started with.
@@SPANNERRASH The more I look the more I see how big the difference is.. brilliant
I love your videos
Thanks Shaggy, I aim to please! :D
@@SPANNERRASH you really do please me, i only found you yesterday and watch all your honda build videos and know watching this build and love learning about motorcycle
Wow, thought it was Andy for a second there . . lol
Mechanic?
Díky!
Awesome, cheers Marek 🙌
Hezký den příteli!
Nice, Bike looks much better with a clear screen. Not sure why put a black screen that just ends up looking like a piece of bodywork.
I really didn't like the black screen. Like you I felt it just looks like bodywork.
Hi there! Great video. I’m in the middle of a screen resto myself. I’m really fussy about finish and have some fine swirls in the plastic. Did you find that you had residual swirls that show up when you looked really, really closely under direct lighting conditions? I’m going to try the 3000 in my drill and start again, then go down to a very fine polish after using a finishing compound, then Meguiars swirl remover. The final polish will be Bilt Hamber swirl remover, which comes in a silver bottle. Agreed - the screen moving about is a proper nuisance….. I will have a glamorous assistant to help me today, albeit reluctantly!! Have a nice day.
Thanks for the feedback. I spent a few hours polishing to get it really clear. I suspect if I looked hard enough I might find some swirls, but I think more polishing with the finest compound would get rid of them. I have ridden the bike quite a bit this Summer, the screen still looks good, but I suspect that the removal of bugs has left it less than perfect now. I haven't looked too closely. :) Hope your glamorous assistant doesn't get too bored, it is a time consumiing thing.
Hey! Thanks for the reply. You’re dead right, it takes time and then some more time. Glamorous assistant is still mercifully unaware of the hateful task that awaits her 😉
I often do handwork while watching videos. Time goes so much faster!
I did this on one of my bikes and it looked great for about 2 years or so. The problem is that the UV really does a job on it. If you do something like a cover, park in the shade... it helps it. It wonder if they actually have a coating that is a UV blocker, that's what we really need.
My bike is nearly always in the shade, but I have thought about the UV blocker idea. Some people have said to paint them with 2k clear coat, but I would be very reluctant to do that, if it yellowed it would be a real problem to get off.
Most good clearcoats have UV blocker. You can get non- yellowing varieties.
Personally I would not sand down the good areas as you are just reverse-creating work. (Providing the finishing polish is used liberally all over then you should not see where it has been blended)
Also good on visors!
(If holding it still is a problem then doing it in situ on the bike is also ok.)
I really like a 900 rr now
They're great bikes, I've had a few.
Your test for me was you using that specific drill motor from certain Store tell us handing, power battery endurance, etc..?
The drill worked out surprisingly well, and the batteries seemed to last far longer than I expected. And although they do get use quite a lot, I am still using them if you watch the lates videos. :)
How does their polish compare with t-cut or even brasso? Seems to me any weak cutting compound or polish would do the job
Good question Adrian. It's very difficult to say how it compares, it may well be a compound formulated for plastic lenses specifically as it seems to do a great job. But I suspect you're right and any weak polish would do it. You may well be polishing for a lot longer depending on what you use though.
If the scratches are very light, you may well get away with it.
It will not, compound come in two stages. PlastX is what you need.
Made by Megs, Mr M Stoops head of training said this product was the right one.
Any idea on if this type of treatment would work on crazing? I have a windscreen that doesn't have much in the way of scratches, but quite a bit of "been left out in the sun" damage.
Thanks!
I think it would, I would start with a heavier grade of wet and dry first. As long as you are patient I think it should work out well.
Crazing is the deterioration of the plexiglass, PlastX is the product you need.
It will take out yellowing, I go 1500/2000/2500..
A medium foam pad helps...heat is not the thing you want.
@@sthildas4857 heat will only make it worse, I know, but I thought there might be something that could seep in and seal up the crazing... Like those windshield treatments for small cracks in automotive glass.
Can I suggest that you put several coats of detailing on to protect it
Good idea. A few people have suggested ceramic coating as well.
I have this type of scratch on my car head lights from the previous owner will what your doing help to remove it and if so what do I get to put this right thank you
It really should help, the kit is intended just for that kind of job. Click the link in the description to look at the kit we used.
Do you know if it works as good with a very dark tinted windshield?
It will definitely work on the plastic. My concern would be if the tint was only on the surface you might wear it off. I think most tinted screens are coloured all the way through, but I would check first. Good luck.
Some givi windshields come with a rubber trim piece that goes around the windshield. Do you know what the purpose of this is?
Hey Kevin, I've noticed those too, although I'm pretty sure its just cosmetic, I don't think there's any practical reason, but I'm not 100% certain.
To prevent the sheild from cutting in case of accident.
My GS screen isn’t so much scratched, but has droplet-like, cloudy marks as if some kind of chemical was splattered on it. Do you think this would work to remove these?
Should work a treat. The kit is originally intended to do headlights. To take the green and cloudy surfaces that they get after a few years. Patience and polishing and it sohould come up like new. I am always really impressed with the difference this makes, whether a headlight or a screen.
@@SPANNERRASH I'm going to give it a try. Got nothing to lose.
Thank you for your response. I appreciate it.
🏍👍
Cheers.
Brilliant job.
Thanks, I do hope it was of use to you.
How many passes with the Polish did you have to do? Thanks :)
I don't think you can measure it in Passes! Using the abrasive each session/pass is only a few minutes, but with the polish it does take some time. I think I spent the best part of 2 hours polishing to get it to where I was finally happy with it, stopping and assessing every 10 minutes or so. It stays a little foggy at first, but if you persevere it comes up clear and bright. Good luck.
@@SPANNERRASH that's great thanks 👌
I feel like I was watching the national geographic very interesting video
Haha! I did my best to make it informative. Hope its useful to you! 😃
Why is this windshield so scratched? It seems like a bad bike storage. But was really nice repaired.
Thanks, I can't say how it got like that, I bought it as it was, with the intention of refurbing it. I was very pleased with how it came out.
Heyyyy I used to daily that one. The windshield is polycarbonate, isn't it? How about fume polishing? The other thing you could do is a simple 2K poly clearcoat.
I used an earlier blade for a couple of years as a daily, you could use the bus lanes so it made my trip to work a breeze. I don't know what fume polishing is, and Google wasn't very helpful so I can't comment on that. As for a 2k clearcoat, you would need to get remove all of the scratches before putting it on, but it is an idea.
@@SPANNERRASHplease don't put 2k on anything other than its real purpose which is car bodies refurbishing, This product bonds far to hard to any plastic and a nightmare to remove!!!
Is there a thinner polishing tool that will make it clear as glass?
Or that's it ?
Hi Teo, its one of those things where you get out what you put in. If you really take your time and work up to the finest finishing polish then you can achieve a glass-like finish. You can achieve a very good result with this kit.
@@SPANNERRASH
I have one more question though...
Why low rpm and not faster?
@@kouvanos Good question, I simply followed the instructions provided with the kit, I reckon a slower RPM partly to reduce sling of the polishing product to keep it on the pad and working for longer.
I love you
Thanks kevin, I am flattered!
Do you think maybe speed would help the polishing? Maybe something stronger then a drill?
Yes, for I would try to get a proper polisher to use next time. It would definitely be a lot quicker.
@@SPANNERRASH awesome thanks I have a bike windshield that's bad and it's over $300 to replace
@@anthonyhawkins9896 Ouch, I hope it works out for you. Take your time and it should.
I anticipate for most this us a wasted effort. My wind s reefs have a protective scratch coating. And when I tried it, completely ruins it. So afterwards when on the road trying to quickly wash off bugs is impossible without leaving new scratches. Even with micro fiber rags
It can be an issue, but with a refresh polish now and again, it should last for quite a while.
What size is the drill attachment?
Not sure, I suspect it is around 1/4" or 6mm. It came in the kit. I hope that helps
What is this product naeme .this tool set and gage of sand peper
It is a 3m Headlight Restoration kit. Here is a link to the one I used ebay.us/ufLqD5
I think this will work on helmet visors too?
Absolutely will work yes. You might want to start with a finer grit though as I'd expect it to be softer plastic and it would be a job to remove sanding marks from.
@@SPANNERRASH Thank you very much. I'll try it on one of the discarded visors and check the result.
I'm sure it would be a good short term fix for a visor. But I believe they have an anti scratch coating which once it has gone means they scratch very quickly in future. Which with the number of times you wipe a visor comes quite soon. :(
Should of done a before and after fitted to the bike
Hi Scott, I picked this clear screen up second hand on ebay, so it was never on this bike until I refurbished it and fitted it. It would have been cool to see it on before and after though. Hopefully, you get the idea anyway. Cheers!
Best way to remove scratches on a screen is to buy a new one.
Great idea, if they still stock them. But could be expensive!
I'm scepticle. I don't see any line around the name Honda. How did you get to on it without scraping Honda
Ha, be as scepticle as you like. I used masking during the more abrasive parts of the process, but also as the part of the screeen around the logo wasn't marked I avoided giving it too much treatment. Basically just a little care and common sense.
Part of the problem is your drill runs at a couple hundred rpm not fast enough
That's a really good point. I was worried about using a faster drill in case it put big swirl marks in to the perspex. In hind sight I dont think that would ahve been a problem.
When it is Macrolon it is a Problem! I work at Covestro near Cologne and make Polyester! In the Neighbourbilding are the the Macrolon Guys and told me Polishing of this is aProblem! The Visier of Helmets is often Macrolon and Polishing destroys it! Other Plastics have not this Problem ! Try a small Area before!
I love Cologne, Ich habe besucht viel mals, I remember climbing the tower of the Dom. Interesting abou the different types of plastics, I know that visors are usually no good as soon as they are scratched. The windscreen seems to have worked out O.
Whatis name of the produits please
Hi, we used the 3M kit. From this link ebay.us/M9Hddb
Should use soapy water!
Nothing like a little lubrication!
Paper towel = abrasive. Microfibre would be much better to wipe the screen with.
Yes, must use microfibre cloths more often!
Good vid but fell asleep 3 times
Glad to be of service.
wash with soap and dry what the result
Great suggestion!
Are you ex REME? Fine mug BTW!
Interesting question, miss off the ME and you have me! :)
Ah! The dreaded rivals, lol. "Spanner rash" is such military jargon!
Very low sound volume.
Crank it up mate! 😆
Those kitchen sponges have abrasive in the green side which loosens and gets all throughout the sponge. Just use a plain sponge. No sense in making more work for yourself.
Thanks for the tip. Anything that makes life easier is always welcome.
not loud enough
Turn your speakers up mate
@@SPANNERRASH you are a bright man for sure...
All that work was unnecessary ....just buy a jar of "Mothers alluminium polish" and polish the screen!....for the final polish , lubricate the polish with WD40.......done! Also those headlight kits are SUPER expensive!
Interesting, using a metal polish instead of abrasive pads. I expect it would work, but I can't see it taking the scratches out. But I will look into it, maybe get some for my engine cases.
@@SPANNERRASH i think they call it "magwheel polish" Its also marvelous on paintwork!
Is this a kitchen sink drama?
Were you not entertained? 😆
Dark screen looks far better than clear one .....😮😮😮
Scratches on my black screen were actuall worse than on this clear one :)
