Plaster's all set up. PoP is an exothermic compound, meaning it heads up as it cures. When I make molds like this, I wait until the plaster cools back down before pulling the casting, in this case it was around 3 hours. The plaster is still very damp and relatively soft. It will continue to get harder over the next few days. This particular casting weighs 28 Lbs, roughly 1/3 of that weight is water that will slowly evaporate out over the next few weeks.

The casting is a bit rough and lumpy, so I'll be sanding it to the exact shape I want. When I get it the shape I want, I'll using it as a buck to vacuum form plastic bodies.
