So, a few weeks back I picked up a mold of a "Soul Eater" on eBay from what was said to be from the TV show Buffy... however I don't recall a soul eater on Buffy... but do recall one on Angel... but, that's beside the point here. Anyway, I thought I'd ask you fine folks here for some tips/thoughts. I haven't done much casting, and looking for thoughts on best products to use, or other ideas. Here is the mold: I've been looking on the Smooth-on site, and I've found a flexible urethane expanding foam called: FlexFoam-iT! It seems to me the flexible foam would be good since this is a rigid mold. It comes in different expansion flavors.. so not sure what would be best. Also wondering about the best release agent to use on this type of mold. Since it's a half face, I was thinking of doing something like Screamline Studies did with their 3-D portraits, and make it look like the head is half buried in the ground. Or open to other ideas if anyone has some thoughts they'd like to share. Thanks!
