It's been about 3 hours now since I put a coat of resin on my fiberglass box. It still has not hardened. I just finished putting another coat that had a lot more hardener in it, in hopes of speeding up the first coat also. Will this work? I've also made a little "tent" with one of those heaters ppl use for camping in hopes of speeding up the process. Fortunately (I think) these coats are only for finishing purposes, I did not use any mat. So if this stuff never dries is there some way I could take it off?
