Ok........I got my prototype spoon made and want to make a mold that will look identical. I have tried the Do-It blank mold and can't seem to get it the way I want it. I know some people use plaster, etc to make molds and would like some info on how to do this.
What are the porducts out there that I can use to make me a 2-part mold out of.

Husky, What is the drying time of the lead when using a Silicone mold? Is it almost instantly like with aluminum?? Thanks

Yes, it hardens as quickly as if cast in a metal mold. Here's a mold I made from it that is nearly 30 yrs old.
