Sonite® Wax is brushed over the entire surface of the mold to prevent the mother shell material from sticking to the rubber mold. Plasti-Paste® mother mold material is then spread over the entire surface. The Plasti-Paste® is tinted with So-Strong® color tints. Once the Plasti-Paste® sets up metal conduit is embedded in the support shell with more material and levelled. The conduit provides strength to the shell and also acts as handles.
