ComposiMold-LT Reusable Mold Making Material, 4 Ounces
I really like the fact that this is reusable. I've gotten fair results, but be very careful about causing bubbles because it's very hard to get rid of them, it's really viscous. The bubbles don't just float to the surface and pop, but kind of stay put and cling. I've heard that using this in a vacuum chamber is very bad news and will foam up and spill over. It has a very low melting point so they don't recommend using any molding material that generates heat because it will deform the mold. I've used resin in it a few times and it hasn't been a problem yet, but you can also pop it in the freezer for a while. I can get rid of bubbles if I bake it in the oven for a few hours, but then it dries out. I've added water to thin it, but it seems to be losing its integrity. I do like it and will continue to use it, but it could be improved.
