I've been meaning to mix up another batch of this stuff. You can thin it, make it conductive, all sorts of things. I wonder if it would make for a nice homemade casting silicone instead of buying the hobby store stuff?

I have done this , the thing about it is that you cannot get very much detail as it is sticky and thick, lots of air pocket in the final mold, also the silicon cauck is made to stick not be slippery so the time spent making the mold is lost only after a few casting.
