Pictured here is the Batman cape covered in another layer of brush-on rubber and the surrounding support mold. One thing to be concerned with when doing a brush-on mold is that it needs support or the material poured into it can cause the thin rubber to ballon out like putting water into a rubber glove.
I make a support out of a paste that dries to a hard plastic. This gets sandwiched around the thin rubber mold. The mold itself should be able to stretch like a rubber glove to slide off my original green Castilene sculpture. I can then use the support shell to hold up the thin rubber mold and pour in a liquid resin for my final copy. super cool fun time!
