last week I purchased some Instant Mold from Cool Mini or Not. Here are the results from a quick, and I mean quick grab whatever I had on my desk and try to make a mold in 15 minutes quick. This stuff really is pretty easy to work with. I placed the sticks I received in 208 degree water for about 5 minutes, pulled it out with a sculpting tool and flattened it with my fingers. Then proceeded to push these pieces into the flattened mold. Waited for the Instant Mold to cool ( couple of minutes), I then pulled out the object. Using green Milliput I pressed it into the mold to make the copy. I used two separate bases to make molds, one was simple and another was complex , to get an idea of what this stuff was capable of. Also one of a Rohan Royal Guard arm bit like the gun they did in the video. Overall, this stuff is easy to use and really does recycle. I tried it and yes it does work when you heat it up again and remold, the arm bit is proof of that. So two thumbs up from me.
Here is a second batch.
