Andy, I remember on several of your videos you talked about endless pinholes during the fairing process. I would love for you to do a pinhole experiment (when you're in better health) by thinning out the fairing compound, and pressing a vibrating electric sander (without sandpaper) on the surface immediately after you've applied the fairing compound while it's still thin. I'm wondering if this will allow entrapped air to escape thus filling the air voids with compound..? I've seen sanders used in this way to remove air from mixtures. I think it may work, at least on horizontal surfaces.
Great video, I have these cracks all over my boat so re fiber glassing and geolocating all over the boat is just way too much!!!! could I do a sample test area with sanding and fairing or using a filling primer, I intend to use Alesseal for my paint materials? I have a 1982 43' Ocean Alexander aft cabin trawler, the cracks are every I look all over the boat.
I had to deal with exactly the same cracks! Sanding down the gelcoat and laying up new csm and finishing it is a lot of work.. I took a different approach which has worked well! Pressure wash/clean the surface thoroughly first. Chips might come flying off; these spots need to be filled obviously. Sand the surface and paint with a well thinned epoxy primer. Smoothen and prime again and finish with a 2comp paint system. So far this has lasted for 4 years and still looks great! Good luck whichever method you choose!
Hey I have almost the same cracking all over my 43' 1982 Trawler, the outside really needs new life, I watched Andy's video I also don't want to re glass the whole boat! My question is did you sand first if so what grit for first sanding, then clean and fare? or use a filling primer? I am going to use Alexseal for my paint materials, I have a ton of boat to address so I am going to do it in sections. any recommendations you have would be appreciated.
Great explanation, Andy. I used Total Tread on my home built skiff. I can’t remember if I put on 2 or 3 coats but after a year of light use it seems to be loosing grip already. I also used Wet edge for the hull and with the humidity here in Florida and we were getting a lot of rain at the time, I would have to wait 3 or 4 days for the paint to cure enough to sand.The paint came out great, but if you’re in a humid area it may take a while to build up coats. I rolled it on very thin as the instructions said.
Great video Andy, I’m still struggling with weather or not to paint or gel. My project is not large but it is a whole 18’ boat that I am redoing. Time will tell. Great video!
Love your videos. I don't have a boat, but I am helping my son restore an older car with a fiber glass body. (A 1971 Saab Sonett.) There is not much instruction out there for cars. I just really find your approach helpful and clear. Thanks.
Great video as always. Just a small nuance if I may -- what product to use to finish off the kind of gelcoat cracking shown here depends on whether the surface is going to be sitting continually (or long term) in water. I am thinking here specifically about boat bottoms, Gelcoat can withstand long term water immersion. Many paints cannot, whether they are one part polyurethene or two part catalyst-type paints (antifouling paint being the exception, of course). The point being....READ THE INSTRUCTIONS for the product you intend to use. I have used one part paints for the bottoms of dinghies with no problems, but those boats are always pulled out of the water after use. Many two part paints warn about long term immersion (even multiple day immersion).
Hi there, I hope your shoulder is on the mend and thanks for your very informative videos. Please keep them coming. With regard to Nonslip finishes, I have always worried about having to sand the grit particles by sanding when repairs have to be made. allot of effort. I have been using sugar crystals to provide the Nonskid texture. Firstly a coat of two-pot then broadcast the sugar while still wet , once hardened another layer of two-pot as top coat. Once thoroughly dried a light sand to knock of the sharp edges of sugar then a thorough wash to get rid of the sugar. This leaves a crater like surface that gives good traction, like little suckers, with no foreign material in the finished surface. Very cheap, easy to repair, and won't wear out your pants. Give it a try I would like to hear your comments....
Why didn’t I find your channel sooner?!? Just in time though… I’m about to paint my dad’s old wayfarer, she had thermal crazing and gel coat cracking similar to the feature in this video. I took a 80 grit flap wheel on the grinder to it and got rid. Layered up with x2 gsm and poly resin and filler to fair it out, with the intention of gel coating to finish. I got distracted by a cheap purchase of a laser dinghy that had a crappy deck, which I sorted out and gel coated… never again will I try that 😂 wow.. it worked but it was stressful. So, thanks for sharing your knowledge.
Great video as usual, thanks. I think maybe you should mention that you can't use 2 pack paint on top of 1 pack, so if the existing non slip is one pack you have to stick with that. Fair winds.
I wish you could write up the steps as you are telling it! Learning by listening only is very difficult, especially for people having issues or like me, as a French speaker haha! Thanks
When younger I spent time racing cars. Paint at 2 feet is different then 20 feet. Worry more about what you are happy with than what your posh friends say. Have a great day
I build race cars. I also grew up in a body shop. I have built beautiful race cars and thought that they looked hideous. Then seen the rich guys cars at the track and realize mine was plenty good enough lol. Now I'm restoring a race boat and rebuilding a crazy jet boat. The little race boat will be perfect up close. The jet will look amazing at 20 feet lol.
I stumbled on this one a bit late. Andy may have this one a bit wrong. Many race boats are full of balsa core, J boats in particular. They are a patchwork of balsa end grain squares. Newer boats switched to no wood core. It was the biggest advertising item as manufacturers switched from wood to better (more expensive) core, transom, stringer materials. I’d take a fully synthetic core construction any day.
My '68 Mark Twain is covered in that. Been looking for an answer to how to deal with this for years. I was hoping multiple coats of high build primer would cover that up. Not really looking forward to covering the whole boat in another skin of chopped strand.
I used wet edge one part paint with soft sand it looks great, but it tends to take a long time to dry. It may cost more for the two part, but it save time . If I had to do it again I would use two part paint.
Hey Andy great content its very helpful. I have a 26 ft 1967 Columbia sailboat. The boat is in good shape structurally, but the crazing and cracks in the gelcoat that you explained in this video are happening on every square inch of the hull and deck of my boat. Is there a way to fix this apart putting a new layer of fiberglass over everything? Thanks
Could you please link to a video you must have about how much of the one part vs. two part considerations applies to below the waterline? We need an education for our 1978 C&C 34. TIA. Burke
Please don’t do it the way he said, degrease the surface and wash, sand with p120, rolle on 3 to 4 coats of and epoxy primer like 545 with no thinners, apply by foam roller, this will seal the crack’s, bigger ones, use some filler, sand all the surface p120/p220, apply 3 more coats by spray if posssible, sand with p320/400 and apply 3 @awlgrip gline topcoat roll and tipping and you will be fine for 10 year’s.
My 32 year old boat is covered with similar hairline crazing but longer than shown here and is only on all top surfaces that were exposed to sunlight. The sides of the hull have zero crazing. I've been wondering whether to re-gelcoat or paint. I think paint will cover the crazing and be less work.
When I looked at the crazing, I thought that you would be thinking that the layup wasn't quite thick enough because it seemed to me that the topsides were bending and breaking the bond at the corners as a result. The flat areas didn't seem to have the same amount of crazing. Will adding CSM actually do much to beef it up? I'll defer to your experience and expertise but I did see this in a restoration I did a few years ago and I beefed up those areas and saw no crazing return.
It's not really a matter of beefing up or making the substrate thicker, more along the lines of removing the compromised material and replacing with new skin to stabilize the surface :-)
@@boatworkstoday OK, I will defer to your wisdom on this but the J29 was designed to be light so it wouldn't have surprised me if there was a bit of flexing going on there at the roof deck. It's been 10 years since I've sailed on one but I remember thinking that it wasn't nearly as solid feeling as my 1970's boat at the time. Love your channel.
I have been wondering about using vacuum bagging techniques to fill gel coat cracks before sanding and painting. My thought is based on the method used for impregnating electric motor coils. The wound wire coil is placed in a sealed tank and the air evacuated which creates a vacuum INSIDE a the wire coil. The tank is then flooded with resin, then the vacuum is released on the tank. The vacuum inside the coil sucks in resin completely encapsulating the individual wires inside the coil. It seems to me the same process could be used on a crazed gel coat deck with so like the following procedure: 1. Clean the surface well. 2. Degrease the surface and cracks with a solvent (I acknowledge the contamination inside cracks may be difficult to remove) 3. Vacuum bag the surface. Use a porous distribution fabric to permit a good vacuum under all areas of the bagged area. Connect fill tubes to the vacuum bag system to the resin container 4. Pull a vacuum on the surface 5. Break the vacuum with resin and observe the resin flow into the crack depth. 6. Sand the filled surface and paint as usual. I’m hoping this method would fill the cracks and surface roughness sufficiently to support sanding to a smooth surface; avoiding the need to add Matt or chase -and-fill each crack. This may be a novel method looking for someone with the vacuum equipment to experiment. Cheers. Tom Fenn Yorktown, VA
To Segway off a bit but it is on my mind with my repair of an early McGregor 17 sailboat. The top sides are a mess and the repair you are discussing needs to be done. Also the two hull halve being a top and a bottom with the top lip overlapping the bottom of the hull. This is screwed and the screws hidden by an aluminum strip and inserted within a rubber rub rail. How would the top sides be separated from the bottom hull? I want to do wood and repair on the inside and if I am considering this much repair then the separation of the two halves might be easier in the long haul physically as the boat is not all that large. Was it common to additionally seal a topside overlap or the screws felt sufficient. Am I facing a heat gun with a vibrating multi tool cutter to slide under the lap joint? I do have an overhead crane type lift in my work area to muscle the top section off.
all you should need to do is remove the metal strake overtop the rubrail, as well as the vinyl rubrail itself to expose the screws that are securing the deck / hull joint. From there it will likely be a matter of getting creative to break and kind of caulking bond to separate the halves :-)
Why is it that I've seen cracks indeed, and a friendly face talking and talking for half an hour, but not a single second have I seen ACTUAL FIXING. Baitclick titles again, RUclips most common nightmare, halas... 😭
I'm on heavy restrictions until surgery next month; not click bait as I've mentioned this several times leading up to this point. For the time being I can explain and answer viewer questions but not allowed to do any demonstrations
I love your videos but I have to disagree with you on the paint over gelcoat part. Only because gelcoat is a lot easier to fix in the long run and will last longer. And if thinned properly using the right materials you can spray gelcoat damn near like paint. To where you just have to hit it with 1000 grit then buff, polish and wax it. Which if you aren’t a painter you’re gonna run it or have orange peel so you’re gonna have to do that process anyways. Just my opinion for doing this work for 17 years now and doing full hull gelcoat resprays every day for the last 2 years including metal flake, pearls and chameleon additives in the gelcoat.
Good input, there's tons of ideas on the web as to how best to thin the gelcoat to become sprayable. Any input from you on this most appreciated. Thanks
It'd be interesting to hear what you do with a 70 year old boat with cracking gel coat. How does one go about that? Sand them lay a couple layers of glass and spray with gel coat? Just send and gel coat?
That's not the typical reason for crazing. Crazing is normally caused by incorrectly catalyzed gel coat that is applied too thick. A dry layer of glass against the gel coat doesn't help, but it's not normally the cause. That's a different failure mode and looks different.

Hello Andy I don't know if my issue is video worthy! But what are you thoughts on liquid transom vs plywood?
Could you please link to a video you must have about how much of the one part vs. two part considerations applies to below the waterline? We need an education for our 1978 C&C 34. TIA. Burke
Hi
If I apply multiple non-wax gelcoats then apply a final wax gelcoat, would it cure?
Thanks
Great info/video - thanks! I was always told that when gelcoat is applied too thickly that it eventually crazes and cracks. Is that true?
It will crack but nothing like this. Far fewer cracks and generally much longer and opened up quite a bit more :-)
Thanks Andy!
If u were to use waxed gelcoat over a layer of glass would u still use primer before paint?
Where you located. Thanks
awesome! I know chuck

I think new gelcoat is the best. If your going to be sanding anyway to paint fill the just do gel coat.
When I looked at the crazing, I thought that you would be thinking that the layup wasn't quite thick enough because it seemed to me that the topsides were bending and breaking the bond at the corners as a result.

I'll try and pin a comment with the materials mentioned this afternoon!! Thanks for the suggestion!
The gel coat with wax additive is often referred to as ‘flowcoat’ isn’t it?
On a racing sailboat use KiwiGrip or similar. Better for traction and sails on deck. If you do Sand, your crew will hate you.
I have been wondering about using vacuum bagging techniques to fill gel coat cracks before sanding and painting.
My thought is based on the method used for impregnating electric motor coils. The wound wire coil is placed in a sealed tank and the air evacuated which creates a vacuum INSIDE a the wire coil.

where are you from?
Are you talking about putting a new layer of fiberglass over the entire top of the boat that's going to be repainted?

2k, all the way .

He absolutely has videos fixing checking/ cracks / crazy, from years ago, posted.
Top strand matting? The search on Total Boat is not definitive.
CSM = Chopped Strand Matting :-)
5:03 five minutes into the video, and still no info based on the title or question???? Uuugggggg
nice 20 thousand fix for a 10 thousand boat
The materials are not expensive, but it is time consuming. If a person is willing to put in the work this type of project is very approachable ;-)
Sanding, fiberglassing, fairing, more sanding, then painting. This is not going to be a weekend project.
Unfortunately not, but it's not expensive or difficult :-)
I love your videos but I have to disagree with you on the paint over gelcoat part. Only because gelcoat is a lot easier to fix in the long run and will last longer. And if thinned properly using the right materials you can spray gelcoat damn near like paint. To where you just have to hit it with 1000 grit then buff, polish and wax it. Which if you aren’t a painter you’re gonna run it or have orange peel so you’re gonna have to do that process anyways. Just my opinion for doing this work for 17 years now and doing full hull gelcoat resprays every day for the last 2 years including metal flake, pearls and chameleon additives in the gelcoat.
Good input, there's tons of ideas on the web as to how best to thin the gelcoat to become sprayable. Any input from you on this most appreciated. Thanks
