Mike - I used "Mann Ease Release 200" https://www.google.com/#q=mann+ease+release+200&safe=off
although just about any mold release should work. The Composi-Mold people say PAM works as well, and that's available in just about any supermarket.

Jeff - that's a great idea; I hadn't thought about dipping the parts in. I think suspending from a sprue or gluing the parts onto a thick sheet of plastic and "floating" that on the Composi-mold should work. Since the stuff takes hours to cool off, it may be possible to brush the Composi-Mold onto the parts (eliminating bubbles and voids) then dipping the parts into the Composi-Mold container to provide support.

I think I should have been more careful with my first experiments with this stuff; it looks like I'll have to filter the crap floating in it next time.

I guess that makes PAM a "food grade" mold release? ;)

Floating the parts attached to a sheet of plastic on top of the Composi-Mold sounds like a good idea too as that gives you a solid base that is not going to break free and float away as it is already floating :)

Well, Composi-Mold is food safe (you can cast food - like chocolate - in it) so PAM would work. I can't use the PAM I have at home because it's butter flavored and it would attract the unwanted attention of at least one butterholic cat.  Maybe I'll get "Vet flavored" PAM next time. That'll keep them away...
