Sugru air curable rubber

And I also found this

http://sugru.com/blog/how-to-mold-precise-rubber-parts-with-sugru

their website sells 100 gram packs for $20 if you were going to be molding something bigger.

So, I think it can be used for making molds, but not for pouring into molds.

Interesting stuff, thanks!

It can't be poured into molds. It's pliable like playdough and dries like rubber in about 24 hours.
