Going to test this with robogen's handplate soon, once I get done making my other pep projects, I will bondo a hand plate and see how gelatin works, then see how it freezes, then see how hot glue poured into the frozen mold works. I'm hoping it will be cold enough to maintain shape and cure the hot glue, but still have time for the glue to seep into every nook and cranny. It's a 1 shot attemp, either it works, or it doesnt.
I want the final casted piece to be solid hot glue.
