I have tried both water based, air drying clay (the kind you might use to make a pot) and an oil based, never hardens modeling clay.

The never harden clay melted just a bit with the vacuum forming and was a mess to clean up. I placed the clay more as a &quot;rope&quot; around the model and that left a lot of nooks and crannies in the formed plastic that clay was stuck in. On one cycle, for some reason, I smoothed out the clay with my finger and that made the clean up much easier. Still, it is a pain and I don't recommend it.

The water based clay seems like it's going to dry on everything and be a mess. In fact it is easier to clean up. The clay did not &quot;melt a bit&quot; in the heat of forming; I think it became a bit harder. Then the clean up is easy with just flooding the formed plastic with water.

I wish I had never thought to try the oil based clay!
