Has anyone used Smooth-On foams to cast parts for mounting? My assumption is that it's not an ideal material for direct contact, but perhaps it can be used safely with a barrier or something. I am looking to cast body parts for dress forms to mount costume to save the time and effort of carving each piece from ethafoam. Also, I'd like to cast hands to replace old foam hands that have degraded over time. These do not make contact with objects, so foam seems okay.

If you've used it, have you tested it?

Thanks,

Jim
