I have fiberglassed the underside of the deck. The instruction manual says to "make sure the fiberglass is thoroughly wet-out, and the weave filled with too coats of epoxy". Would that be a total of 3 coats, one wet-out coat and two fill coats, or just one fill coat? Does it really matter? I do not wish to use extra epoxy if not needed. Reason I ask is that I have about 1/3 left of the epoxy, and I still have to glass the deck, and apply fill coats to the hull and deck. Will I have enough epoxy to finish this project? Otherwise I am very pleased with the way the boat is coming out.
