That resin looks pretty good, my casting book says I should be OK with a silicon mold and resin, does that sound right to you? Or more directly, what kind of mold material do you use? I've found the caulk that I've been using to be flexible but not very durable.

I remember of a technique where you mix in some plaster to give the mold strength but I haven't been able to get that to work lately. Any tips?
