This show covers how to repair fiberglass stress cracks on your boat using polyester resin. Previous episodes go over other types of fiberglass repair using West System epoxy.
Thanks a stack for this video. I am a south african lady who had a stress crack in her pool...got a repair kit, read the instructions and was a bit overwhelmed...watched this video and repaired my pool...by myself! so proud. :).
+Toni Joubert That's awesome Toni! Well done ;-)
I am in the UK. Rebuilding a 1970's Lotus Europa. This video has been invaluable. Professionally presented so that even an novice, like me, can feel confident tackling fibreglass repair.
This is a fantastic video which thoroughly covers every step of stress crack repair, and the closeup camera work is excellent. I'm going to use this video as my primary reference when repairing a similar crack in a corner of my deck. Please keep up the great work.
I have done some fiberglass repairs to a small degree before. But I have never heard such beautiful guitar music playing in the background while doing so. As a guitar player myself I am twice blessed by watching your channel.
You have to be the Bob Ross of boats! Thank you for sharing your expertise. I was looking for repairs for my van with a fiberglass high top. That is how I found your channel, and now you have a new subscriber! 👍👍👍😁😁😁
Your series of videos are very informative and helpful. Your use and explanation of the why for many of the products and techniques helps avoid the pitfalls and gives some solid advice and direction. Many thanks.
I have done fiberglass repairs years ago on truck frontends and corvettes. I learned a lot from your video, thank you.
When I find "dry laminate" layers, I take a small drill bit and drill into the hole, then mix a very small batch of resin, then inject the resin into the dry void with a needle. You can actually watch the resin saturate the dry laminate from the surface. It works well. For areas where there is plenty of glass, but someone just didn't quite brush/push out the air from the glass, the adhesion and structure seems to be absolutely fine. Overall, much less sanding/tooling and less disturbing of the surrounding good glass laminate.
ok but that doesn't provide any structural integrity -- I mean I guess it's better than leaving it as is but... i'm not sure
@@IrregularPineapples He mentioned a very specific situation where there might have been dry laminate layers where maybe they didn't use enough resin or they did not brush the air bubbles out, but there was enough glass, which is where the structural integrity comes from, it just needed more resin, if that makes any sense, hope that helps explain it a bit better, take care and have a nice day.
Hey Anthony, I use a 1.4 tip for repairs (would not use this size for an entire boat though :-) I mix non-waxed laminating gel with a product made by Duratec (high gloss additive). 60%gel W/ 40% Duratec. This additive works as a thinner as well as a curing agent to allow the gel to fully harden. With the 1.4 and the flow about half open with a tight pattern 30psi it sprays very nice. VIP Catalyze the mix 2%. Or try going over the tacky gel you sprayed with PVA. I never use gel with wax anymore.
Thanks Andy! Love your tutorials! Best Fiberglass work Ive ever seen!
I have built in repaired a TON of fiberglass. I have learned i know nothing, so SUBSCRIBED.
I live in the UK thanks for your videos there a great help on my boat restoration hadn't been for you would have had to pay someone to redo my fiberglassing on boat keep them coming
I am always afraid to mess up. Your videos help me enourmly to even try to start such work. Even more so importend as I have not the funds no more, after the divorce, to hire Professionals. With your videos, I can manage to fix things and thus not give in to in live. THANK YOU, ROVER
You make fiberglassing look easy, bet if I tried to do it, it would look much harder to accomplish!
Awesome video! The way you demonstrated reminded me of that old tv show with the artist Bob Ross and his painting.
Glad I came across this youtube. Great presentation and full of material for those taking on a project like this. GOOD JOB!
Thank you very much for this one. Love watching people that know what they do with ease.
Your videos are relaxing and satisfying to watch. I wish I could be this calm when I work on my boat!
You are an excellent teacher. Thanks for your work.
Excellent how-to. Easy to follow and understand.
thanks for the videos you have truly save me thousands of dollars
Just pulled this one back up to show my 13 year old son what we would need to be doing on one of our boat. As You were applying the faring compound my son said " He sounds like Bob Ross". By the way he loves Bob Ross.
This guy really deserves his hits. Well done.
Mate thanks for this fantastic presentation. Really appreciate you sharing your expertise !
Great job on this tutorial. It was well produced and easy to follow.
Ive been watching you for awile now and youve helped me alot....i will continue to watch....
In a pinch you could, but it's going to be a much harder surface to sand and it wouldn't smooth out as nicely (will still be a little porous). I've done it, but try to avoid it when possible. Thanks for the comment!
Sir , you are indeed a very patient man, for this is a labour intensive hand work. I like the manner you run your finger through the finished patch to check for high and low patches and you seem to detect them even if they are so shallow. What worries me in this type of work is that concerns me to know how new resin would fuse in with the old resin laid years before. Last week a colleague of mine lengthened and widened a fibreglass boat and he uses a special resin that would bind and fuse itself to the old resin laid years before. I am not familiar with this product but it is indeed useful to know especially when one lengthens boats to a larger side as the adhesion and fusion must be reliable. Congratulations for your hard core structure and also for your finishing.
Thank you, I'm restoring a Baja VW Beetle. Old fiberglass.... Gotta love it......
That looks like hard work ,I'm working on my Healey wide body ,stop by Thanks Radu
CSM for the finish layers as it sands smooth for finishing (gelcoat or paint). But generally I use 2 types of glass; 1.5oz csm and 1708 bi-ax
Thank you!!!
Thank you!
Really great VIDEO, never did epoxy resin, lots of great information. Thanks William
Thanks Andy i think i had to open up the flow more on my gun. ill let you know how i make out, im going to be at the boat yard next week. Thanks again
awesome..I am going to use this info to repair my meyers manx buggy..thankyou matey.
Great job on the video, good level of detail and explanation of why you were doing each step.
About ready to repair 2" cracks in hull of '75Sunfish then gelcoat entire hull. Thanks for giving me much insight about wht this entails and especially confidence! I will be reviewing your vids a few more times beforehand but your details have been great! Nice work! Many thanks.
this guy is the bob ross of fiberglass.
You're a great instructor!
always a pleasure watching your video's. Thx a lot for sharing your knowledge and experiences
Great videos! Very well done. You explain each step and why you are doing it and then each step is nicely shot on video.
This is super, now what steps would come next OR which video would take us thru the primer and finishing process?
Thanks for all the information, great job!! Cheers from NorthRineWestPhalia, Germany
Thanks mate, really good and informative. Restoring my boat purely using the school of Boatworks Today.
Great instruction Andy.
Hi. I have been doing truck hoods for 25 years and am trying to improve my skill set. We mold using gel coat but during a repair we use resin and Vette Panel Adhesive which is more or less body filler with extra resin. I understand the differences in the poly resins but why do marine repairers use gel coat for repairs? It seems to complicate things IMHO. Total quality repair yes but in our industry we'd get about 2.5 hours to have that in the paint booth and our jobs sit outside in the sun and go down the road vibrating every day. Great vid and thank you
You do unbelievable video's for us cream puffs but please do a video on the touch up painting process as well. OR if you already have one point me to it. Again great job!!
Fiberglass and finishing it has always been like a mysterious black art to me.
That was until I came across your videos.
Thank you for making them and sharing your knowledge.
I'll be working with vinyl Ester resin. Is there a certain type of gelcoat I need to use?
Your videos are really great man! Good work, keep it up, I'm learning a lot!
Thanks for the video Andy. You do great work, and your explanations are excellent. Looking forward to the next video. Tony R
really enjoying your show - thanks for taking the time to do it
Great one, exactly what I needed. Thank you.
A Good Instructional Video. Thanks very much
A good tutorial explains tools used etc. What grit sandpaper on the grinder, or was it even sandpaper. Would like to have seen the dremel in action...that's why I'm here. Also like to see what your mixing together in your compound. Again, that's why I'm here. Like a cooking show, I want to see the mix as it happens. Good insight on the color tip offs about too little or too much hardener..
A total list of the items you used to create this repair would be great!
very nice work
WOW incredible talent, great skill... Thank you so much...

Quick question. I recently discovered a soft spot on the deck of my 2002 Sea Ray 340, due to the previous owner had an accident. Removed the hatch and ground out all the mush, vacuumed it all out.
I had repair a crack in the Fiberglas and had to sand about a square foot of factory anti-skid (diamond pattern) the first problem I’m having is the repair epoxy is bleeding through the factory color matched gel coat. What do I use as a color block? Then I order the factory anti skid pattern mold from james town dist.
Do you think it is possible to blend in a square foot of anti skid perfectly, in the middle of about 6 square feet of anti skid?
Thanks! Really enjoy your videos!
Excellent teaching. Thanks!
Excellent explanation
very helpfull ,thankyou , well explained.
My biggest problem with stress cracks is what has let go underneath to allow the cracks to form?
I learned lots, thanks. Great video.
I haven't simply because I didn't want to take the chance that it wouldn't work :-) PVA, wax or other additives are inexpensive compared to the time needed to re-work a repair.. Not saying that it wouldn't work for a very small patch but I wouldn't recommend it for a repair of larger size..
Very nice, thx for sharing
Thanks for the informative video. Can u show us how to paint the repaired area? Also, i thought gelcoat was the top final finish that covered the surface of the boat. In your application it sounds like gelcoat is only used to cure the glass. Thank you.
Hooverhoff Typically gelcoat is a top finish surface, but it can also be used in place of PVA to seal glass beneath it to allow full cure. I could easily have used PVA in place of the gelcoat for this repair, but I had a bunch of gel laying around that needed to be used up :-)
I thought I knew everything about composites but I’m finding out now that polyester and gel coat is a totally different process than epoxy and urethane prime/ paint.
Brilliant video and certainly learning a lot. Too much epoxy to learn haha
Thank you from Turkey :)
6:50 'Just taaap it in, give it a little tappy, tap tap taparoo' - HG
thks boatworks - assuming i got the gelcoat off the boat (16 grit on a grinder?) is it important to seal the raw fiberglass with gelcoat before painting, or can i prime w 545 and finish. I want to get this right so i don't have to come back to it thks again for your vids
Peter Ekstrom If the surface was taken down to bare glass, you'll most likely have a lot of pin holes if you go straight to priming. Might be a good idea to go over the surface with a skim coat of Awlfare LW to smooth out any defects and fill holes. This can be applied with a plastic trowel, has good working time and sands really well. After this is lightly sanded then spray 545. Might have a few more pin holes, but just repeat the process where necessary. www.awlgrip.com/products/fillers/awlfair-lw.aspx
Very Excellent
I spoke to west system and they said that you could use polyester on top of epoxy, provided you let the epoxy cure for at least 18 days at 20 deg C.
at 18:04 you flipped us off bro good video
Awesome videos!! If I send you some photos of some stress cracks on my boat, can you tell me by looking at them if it's just the gelcoat that cracked, or if I have to actually repair the fiberglass? The cracks are much smaller than in this video, and were caused by a collision with the dock. Thanks in advance for any help.
Sure, go ahead and send them to my Facebook account :-) Also, please feel free to 'Like' the page!
Good job
Nice job on this "stress" crack. Couldn't have done it better myself:)
I do have a question about procedure in repairing a noising line on steps in a fiberglass swimming pool. The crack is 4-5 inches long horizontally along the edge where the step and riser meet. It is not however, a stress crack, it is fully cracked through so that we have a leak. I applied a temp fix with epoxy putty [underwater type], but now it'll need a permanent approach. Could you steer me in a specific direction. I have a pretty good idea on how I'll approach, but any other expert opions are entirely welcome. I don't want to do the job twice. The pool is only 2 years old and in installed in-ground. Thanx.
Greg
You sir are the master! Tx!
Great information , I am a new subscriber and fan of your videos!
These are fantastic videos, thanks so much for making them!
Thank you for your sharing. Lots of helps.
Did not find it on your page but you should offer weekend course on this. I'd be interested in taking them if close enough?
Thank you for the quick response. :) what I was asking is would a coat of pva over the glass work the same in helping it to cure, would it keep it from gassing off and slow the cure? An old timer showed me the pva trick, it seemed to help with blending the color better, I was putting in a bow thruster and using flag blue. Is it the heat of the gelcoat kicking that does it?
Thanks for this, and for taking the time to go through in detail, much appreciated.
Good point to bring up, unfortunately it's one of those things that got edited out of the video :-( There are 2 large aluminum backing plates on the underside of the captains chairs which are now mounted with stainless bolts, washers and lock nuts!
Great instruction. Thanks
I have a 1973 fiberglass boat from ss sears I AM ALMOST READY to prime the bottom should I role resin everywhere first or just prime it
Love your videos and subscribed. I've seen in other videos that you alternately use woven roving mat and csm for repairs. What about this job made you device not use any mat? I'm under the impression that csm takes shaping better, but the mat is the strength.
Thanks... you're a big help.
love it really helpful hope my patch comes out like yours
you're a true craftsman!!
Could you use resin with wax on last coat instead of gel coat to seal it ?
Need help. Just got old wooden boat , was long time in water, prettymuch rotten but not completely. Brought it to my yard, now thinking to start . Give me advice please, start it from top or better from bottom .?
Thanks for the response. If you were not repainting the entire boat, how would you match the repair to the existing white top coat?
I'd just continue using gelcoat rather than paint and spend the time getting the color matched to blend :-) For this repair it just happened that the paint I was using was a very close color match to the gelcoat.
this guy is a pro
I understand you did this video 8 years ago but just wondering if done today you’d use a microfibre resin mix to fill that hole? Is that perhaps the same problem with too much resin and not enough fibre?
Do you have long videos because i am rebuilding my floor and transom in my 1966

Is there a reason you tap it out vs. rolling it out? I'm guessing it is just easier and why dirty another tool?
