PLEASE NOTE: NecroClay™ is NOT a wax replacer. It is used in conjunction with NecroDerm™ Wax Replacer. Its purpose is to "pre-fill" deep defects and as a medium to sculpt missing features.  It is the best restoration clay available. A blend of oil based clays created especially for mortuary work, it is must have for the serious restoration professional. Use to fill larger voids or re-create damaged facial features before finishing with NecroDerm Compound or NecroDerm Prosthetic Skin. Please note that the flesh color can vary somewhat due to the manufacturing process but this does not affect performance. Must be finished with NecroDerm compound and NecroPAX  for a complete repair. Does not dry out or harden, but may be "fixed", or made more rigid, by coating with light coat of super glue.  This is handy when re-creating missing facial features. 4 ounce jar.
