Does anyone have an idea of aprox how much epoxy it would take to cover the hull with epoxy?  I am just fiberglassing the hull and want to make sure I do not run out mid way thru, I have about 3/4 gallon left?  Is that enough or cutting it too close?.  I also have to give the interior and top a coupf of coats as well?  Not sure how well this stuff spreads out or saturates?
