Apply clay to the casting, then sculpt to create the zombie face appliance model. Once the face appliance sculpture is finished on the epoxy casting, apply Ease Release® 200 release agent. Allow it to dry and then repeat. Mix and apply EpoxAcoat® to the sculpt to make a 2-part mold.
Mix equal parts of Free Form® Air epoxy putty thoroughly and apply to the tacky surface of the EpoxAcoat® Grey for support. Let it cure for 4 hours. After curing, carefully separate the epoxy shells and clean out the initial clay appliance sculpture.
