Thanks for the comments everyone! The wax casts prefectly. It's pretty much a professional "toy" wax. It's the same stuff the Star Wars, GIJoe, etc. figures are sculpted in. Actually the first couple waves of Robot Heroes were done in that wax too, not sure what the later waves were done in.
These are great! I'm glad you posted some of the images, but we'd like for you to attach all of your related images. Thanks!
I don't collect the RH line, but that Skullcruncher was part of it I'd snatch him off the peg in a heartbeat! Fantastic work sir!
