Claymation Armature Tutorial - After the wire armature is complete, I add magic sculpt, a 2 part resin that hardens in about 45 minutes. It can be smoothed with water, and becomes completely hard in about 6 hours. Once hardened, it may be drilled and carved. I will add a coat of acrylic paint, then add the clay. The acrylic paint prevents the clay from becoming discolored.
