I will be doing a small fiberglass repair next weekend. Its a little bigger than a sq ft. I'll require a layer or two of fiberglass. I intend to finish it with a layer or two of gelcoat. Its that second coat of gelcoat that i'm wondering about.
I've got some "waxed gelcoat" .... gelcoat with wax mixed in. I've used it a few times already. It air dries; my understanding is that the wax migrates to the surface so that it will cure. So no need to overspray with PVA. I've only used it as one coat so far.
With this stuff, what about a second coat? Can I do it while the first is still tacky? or will the wax interfere? Is it better to wait until fully cured, and clean with acetone before the second coat?
or should I skip this stuff altogether and go with "regular" gelcoat and spray the final coat with PVA?
