I've worked with this stuff my whole life and built up to 57' hulls
with epoxy. I'm assuming your hull is wood, if so I would seal it with
a coat of epoxy after fully cured you need to remove the blush from it,
sand, white gas (dry cleaning fluid), even soap and water will remove
it but be careful water doesn't mix with any resins. The fiberglass
material you choose is important I would use a 6 to 10 ounce cloth if
your working alone 38" wide so you can handle it.Apply a roller coat of
epoxy to your boat drape or roll out your fiberglass into the epoxy use
all tools mentioned to apply your material to epoxy.
