Maybe someone has some experience with gelcoating fiberglass.
I just repaired, refiberglassed and gelcoated the bottom of my HB Freighter.
My question is this: after the final gelcoat layer with hardener, do I need to wet sand it? I think wetsanding would smooth it out a bit but I am not concerned with cosmetics on the bottom of the canoe. So, if there is no good reason to wetsand it, I will not. It is pretty smooth, for an amateur fiberglasser, that is.
Is wetsanding like a finish polish? Does it just smooth out the hardened gelcoat?
cosmetic thats all, the gel coat is your final sealer.
