What brand to you use?!
Read the entire posts! Lots of good info. I didn't buy the centrifuge but do heat the epoxy accelerator up before mixing. Unfortunately this heating causes the mixed epoxy to start to set sooner so that it's harder to pour into those tiny spaces. (maybe I will try heating up the base, not the accelerator in the future!) Anyway, I do the best I can pouring slowly the thick epoxy into the impression and when finished I then place the impression (full of the epoxy) into a pressure pot and fill it with air at 30 PSI and leave it there for 2 hours until the epoxy has set. But frankly, we have stopped using the epoxy because of the mess.
