It involves some work.....
Make a urethane casting in the newly repaired mold. Smooth-On\'s "Brush-on 40" is a good choice.
Afterwards....Stuff the casting with plastic bags and remold it with a flexible material such as silicone. Then once the new mold is made, pour your clay (pref, a firm grade) and do a slush...
Get a thickness of up to an inch. Then fill it with rigid foam. You now have a light weight head you can retool the surface and remove inperfections/add detail. Once you\'re happy, do a typical stone mold.
Hope that helps....(I left out many details.......but that\'s it in a nutshell)
