I use a lot of that super77, but to laminate my
SDM tug hull pieces, I used 30 minute epoxy.
I fiberglassed the hull, using epoxy resin, for a nice finish.
Is your hull coated with thinned 30 minute epoxy? if not, where do you get the epoxy resin. All I have on hand id Bondo brand fiberglass resin I use on wood and it eats up foam.
