Hobby shop clay works as long as you don't get the kind that hardens when you bake it. It can be hard to find the old style oil based clay, but it works just fine. Make sure to get good coverage over the clay with your PVA or the oil in the clay will cause your gelcoat to alligator.

I'm not that much into it. I'll take a look at the box to see if there is a temp rating. I just put it on the mold and glass over it :)

I have been told that you should use a low sulphur clay when making silicone molds. Do not know if there is any reason to apply this advice to epoxy or glass. Sulphur in the clay can effect curing of silicone.
