I missed that part about keeping the fiberglass in a bag to keep away dust and humidity. I had left my roll of fiberglass in the shop uncovered--through all my sanding.
I am about to fiberglass the top of the deck. So how should I clean the fiberglass. Should I just shake it to get the dust out, or should I wash and dry it. I am thinking the dryer might melt it. Since I wanted to put it on tomorrow, I don't have time to wash and air dry. I am thinking the weave would unravel during washing anyway-maybe a gentle handwash, but that would be a real pain for such a large piece. Vacuum?
