6. Mix your resin, if using ComposiCast Urethane Resin, mix in equal parts by weight or volume.

More information about applying Mold Release to your Model:
Applying a mold release (or release agent) will allow your model to be easily separated from the ComposiMold. Applying a mold release to the mold before casting will also minimizes wear and tear on the mold. This is important if you are using the mold to make many reproductions.
