For those of you that make your own props, such as corpses, body parts, food, guts, etc. What are some of the hardening agents you use to coat your props to make them rigid and durable for many years.

Larry, I noticed in one of your movie clips you have a guy who mixes up various food and coloring, then adds hardening agents to make them last, what are some of the recipes.

My theme is a huanted hospital, so I want to make my own patients on surgical tables with guts or brains hanging out.
