the other day my father and i were at lowes and picked up some Elmer's fiberglass resin. i used it today by coating my helmet's inside and did some minor outside fiberglassing.... i know for a fact i mixed the hardener well, an hour after i worked on it i wnet to the workshop to check on it and ... well its still wet. now the residue in the bowl i mixxed the fiberglass parts in had a lining of a gel (not throughally hardened) resin. now take into accont that the in NY it 35 degrese and we are working in an old barn so no modern day heating ( wood stove which wasn't on) so im figureing that the weather is a part. but i have used BONDOS fiberglass before and i had no problems with the weather.... just wondering if any one has had this issue?
