Paint Depth test DA vs Rotary Polisher
Вставка
- Опубліковано 20 січ 2021
- In this video I test the paint depth on this panel and run it through a series of tests. This can be beneficial to a detailer who would like to know how much clear they have to work with and what the outcome will be when using different products.

Thanks Dave, always a great start to my day seeing your videos.
Definitely having a rotary and DA are a must if you are doing even the most casual detailing.
This is one of your best videos, thanks KB.
Thanks for that mate
Love the advice and tips!
Thanks for an eye opening video mate.
I am watching your video..I am gaining knowledge..Thank you very much brother ... My congratulations to you
DA's good for beginners.
But the Rotary is king.
I have to disagree. So yes a rotary can help save time on cutting but a DA with a good wool pad can cut but also finish nice enough to only need a quick polish to jewel the paint.
Also with modern cars the paint is thin enough that if you cut with a rotary, you diminish your chance to polish more than once after that.
I still use rotary, especially on gel coat. Without sand paper and rotaries on boats, RVs, and planes you'd be there forever polishing. Freshly painted cars are great spot for rotary as well, but to finish the paint, I still feel da is king on finishing.
Bad ass information thanks! 💪🏽
Dave, Wow that's a lot of energy you did put up in it, THX ! 1 question though: what is the effect of the Da/Rotary and what is the effect of the pad? Any idea? Frank
Could you do a pros and cons of vinyl wrap vs full car respray? Awesome channel man thank you.
Hey dave love you videos! You actually motivated me to paint my own car and it looks great. When i buff and polish the car i still have sanding marks. What would recommend i do to remove the sanding marks if i buff and then a few days later the sanding marks become visible again. Love your content!
Hey mate what machine and pads are you using. Could be that it’s not course enough.
I think for the compound and rubbing the rotary works well and for the liquid polishing and wax DA polisher works well?
What were the measurements before and after on the bonnet panel? 🤔
How do you know when it's time to spray new clear coat on bonnet vs correct and polished it? I've seen vids where they respray clear on slight faded bonnets and have seen vids where they correct/polish on really peel looking bonnets.
Super video, you have cleared up up many wonders of mine.
As a matter of interest do you know the amount of lacquer on a European car compared to to a Japanese car or Asian car is please. I have heard they are different what are your views on this? thank you and thank you for the great video.
Thanks. Euro cars normally have over 150um Japanese cars normally have around 100.um. Also euro clear is mostly harder where as Japanese clear is quite soft and easily scratched
Great, well thought-out video! I'm a beginner and learned how to clean a paint gun from your instructional video. Today's video is timely for me as I've been wondering how many coats of clear to use on my project (car restoration). I'm planning to use a HS clear and the TDS says to apply 2 coats. I've seen a few videos where they say not to apply more than 2 coats of high solids clear because "that will just get you into trouble." Your data suggest that 1 coat of clear is approximately 25 microns and that cutting and buffing will remove at least 13 microns. I'm guessing that I should apply 3 coats of HS clear so that I'll have at 50-60 microns on my final job left after cutting and buffing. Is that what you recommend?
Hey mate. 2 coats is definitely enough a third coat won’t hurt though.
@@customspraymods Thanks very much for your reply. And thanks for your helpful videos!
I have rotary and da and in my tests i get better and faster results with long throw machines than a rotary. Rotary only for spot working and pad drying for me. And yes i do wetsanding for cars too. The reason why your rotary spot had "more" clear coat because the paint was over heated and the paint swell.
Rotary can not cut faster than orbital. Impossible.
Nice video, question, what exactly is that magic compounds applied at 6:00? So many compounds on the market these days... Thank you, perfect timing for my projects... Getting ready for warm weather.
That was Osren 56 great stuff
@@customspraymods Wow, thanks for the quick reply, shopping for some now! Thank you have a great weekend!
Can you do a video showing how hard it is to burn through paint with the rotary?
I’ve burned through new paint. On a flat hood/bonnet it is safe. Wool pad is most aggressive and if you bump into a curve with the pad perimeter or if you hit the panel edge with the pad spinning in the wrong direction it will burn. When you burn through the machine digs in and it only takes one second.
It’s not hard to burn through paint at all with a rotary, even easier with foam than wool, and you don’t need compound to do it, the friction from the foam pad is all it takes.
Must buy one of those meters find out how thick my single stage black is. Anyone tell me is it safe to wet sand a 15yr old respray? Was thinking 2000 then 3000 followed by DA and cut compound. Cheers
Very good video... I’m assuming you used 2K?..
Yes it was 2k
I agree rotery is the best
Is it safe to use 21MM DA polisher for wetsanding? I see u wetsanding with it, Share your experience please and speed recommendation for it.
Yes I've diver that a bit. I use very low speed
You could find the standard error of the data using excel and graph the results. The variation In your data could explain why you saw some strange data. You can see from a scientific pov whether the results were statistically significant or not.
what's a pepa?
Moral of the story= clear coat your paint job with a rotary polisher 😎
The rag company and DIY detail channels disagree claiming that random orbital polisher cuts faster than orbital and that orbital can do more damage again than orbital. Silly boys.
30 second work time only with a DA , you'll get hazing like you did
Ah I don't think you are measuring what you think you are measuring, a rotary device has a different wear rate depending on the distance from the centre as it goes trough a larger linear travel per rotation (that 2*pi*r thing), in short so you would expect your wheel to cut deeper per revolution at the periphery than in the middle.
You need to measure at more than one point to get the average cut depth per second/minute/whatever.
If you know how to use the rotary the da is useless
What do you mean?
@@Sr-gw4my I mean that { if } you know how to use rotary you don't need a da ...
4:31 good kid? hahha
