Measure out a sheet of aluminum foil to 16'' x 12'' and fold it into quarters to hold the model during the mold making process.
Recommended: Wear protective gloves and glasses.
Use the glue gun to put some glue on the bottom of the dowel. Firmly press the dowel onto the center of the foil base for one minute to ensure that it adheres securely. Once glued down securely, seal the top and sides of the dowel by brushing on a thin, even layer of Sonite® Wax. Use the hot glue gun to seal at the juncture where the tube and foil meet. This will prevent the liquid rubber from escaping.
