cut and place layers of epoxy infused fiber mat pieces from small size to increasing sizes...
isn’t it supposed to be the other way around? I think you want biggest pieces with max surface area directly over the hole.
Thanks!Make sure you really scrub the epoxy patch well with acetone before rolling out the gel coat. Getting a good bond over epoxy can be tough because it develops amine blush when curing. I personally only use polyester resins for repairs when I plan to gel coat. The easiest way to lay down gel coat for the first time is to use a tight grained white foam roller. They come in a 4"wide version with a rounded tip that doesn't leave a hard line. You need a roller without the basket for them. Epoxy works well for chips and deep scratches with a little resin tint added though.
My son marine tex'ed any scrapes and grooves, then sanded the entire hull with a body profile sander at a 220 grit, wiped it with acetone. My friend sprayed it with an HVLP sprayer with 3M disposable tips and bags. Thinned the gel coat with acetone. Two coats were sprayed then a coat of PVA.Looks like you sprayed it with just an hvlp? How did that go? Did you rough up the old gel coat to give it something to bite on or remove the old all together?
Thanks, my son did the bulk of the work. He doesn't want to put it in the water it looks so nice.Marshmaster, this hull Turned out beautifully, nice job!
