Sticking with the frugal builder theme, I decided to make the mother mold out of expanding foam.

DOW's Great Stuff really is great stuff! Pun intended...wow lame!

Obviously, it wont get a nice forming mother mold, but I just needed to hold the curve of the Nihilus mask. You can try to spread it on, but it is difficult so try to spray it nicely. You can also mist it with water to speed the curing and make it expand less.

Demolded

I slush cast a prototype with smooth cast roto....that I opened 13 months ago!! Needless to say, it is very old and should cure bad. I have found that this stuff will work for A LONG TIME. Since I spent $10 on molding supplies, I wasn't going to use my good smooth cast! That would be fiscally irresponsible! For using silicone caulk, expanding foam, and 13 month old urethane, it looks pretty nice! Just dremeled the eyes out quick and lightly sanded.
