Brent@Brent You might be able to use that mix for some projects, but because it gives off a smell of Acetic acid, you won't be able to make things like custom IEMs or teeth for cosplay. Also, the silicone may contain solvents that could be absorbed by the skin, so you cant mold it around yourself. In addition, you'll have to go through the process of mixing the silicone and corn starch every time you want to redo your project, whereas you can simply melt Instamorph and retry.
