Hey guys. I purchased a Predator bust which was casted in resin which i plan on painting the liquid latex from monstermakers over it and pulling off a raw mask from it. Now i was talking to Hez about his bio molding process and he mentioned that I would need to foam fill the raw mask. I tried doing a search but the results came up short with threads that didn't have anything to do with foam filling a mask. So I was hoping maybe someone would be able to help explain the process of foam filling a mask that i'm simply painting latex and pulling off a bust.
