So I used the alumilite hs3 silicone. Its a tin cure, 600 bucks for a 5 gallon bucket.
Rediculous, I know.
I created my knee mold out of it, and got about 25-30 pours out of it.
Its shot to hell. It starting to look like old skin. Wrinkly and poor surface. I obviously cant go any further with it. Now the problem is kind of two fold.
1: Some of the things im making a mold of, are themselves cast. Such as I am making master darts, to make more molds, so i can pour them 10 at a time. The rubber/resins arent curing with the platinum.
2: Id like to do brush on application with it.
Well, my platinum isnt curing against it. So I needed a tin. Thus the HS3. But further, the tin cure stuff seems to not be giving me very many reproductions before it goes to hell.
Im getting to start some molds for my webley, and another for my knees. What would you guys suggest I try. Or is 20-30 just the most im going to get out of a mold? Whats the best tin cure that can be thixo'd
