I had to use a two part epoxy to sculpt a tail for a carving as the tail was just too thin to carve without risking breakage. My problem is that at least in this humidity I can't get the epoxy to harden. I made about four tails so I could pick the one I like the best and none of them will cure completely. Should have hardened in 24 hours and I am already up to 48-72 hours and none are hard enough to shape and texture.
Any idea what I can try to speed up the curing process?
