Peeling fiberglass surface

Wax in polyester is used to allow seal the resin from the air to allow the resin to harden without a sticky surface. If a getcoat is used as the first layer in a lay up schedule there is no need for wax. I haven't checked costs but I'd guess that the resin containing wax might be a bit more expensive then the untreated stuff so logically a factory would use "un-waxed" resin when using get-coat.

The finish on the seats and interior hull are sprayed on after they both came out of their respective molds. That would explain my problem perfectly.

Then if you are worried about the fiberglass absorbing water, you can paint on one or two coats of activated epoxy resin. Finish by applying two coats of high build epoxy primer, sand, do any minor fairing with epoxy or polyester filler, and finally spray on two coats of two parts polyurethane. Sounds like a plan. I'll probably just do the seats for now. They won't match the bottom and sides exactly but I think I can make it look ok. And hopefully it won't peel off again. Thanks y'all :-) Rick |
