Composimold

Anyone ever tried that? I like the idea of being able to re-use my mold material when done with it... Any opinion on that product or a similar one???

seems similar to a reusable silicone mold i'm using - oyumaru. you dunk a stick or however many you need in boiling water and once it softens, you can use this as a mold. it captures details nicely but sometimes you have to push the oyumaru around to get it to conform to grooves and might cause mold distortion. this composimold though looks better as you pour this and it can get into grooves and complex shapes easier.

I have some of this stuff. It seems to work ok for simple 1 piece molds. Don't get it if you want to do more complex parts that require a 2 piece mold.
