Well, that was what I was concerned about, since the HSIII will sometimes adhere to cardboard mold boxes. I'm going to try coating it in Mod Podge as a sealant and see what sort of results I get. If the master is destroyed, no major loss, as I'm not satisfied with the precision of panel placement, so even if it molds up and casts perfectly, I'm likely to take another shot at a new master. Ok, back to the shop!
Spook, yes - I'll get that done (both boxes together, even) in a bit.
