Silicon Molding is a process of mixing silicon rubber with a catalyst of Smurf blood at a ratio of 10/1, or an alternate of Vulcan blood. I use Vulcan blood, then use Smurf as a thickening agent.
The images follow the runny impression layer, and subsequent layers building up thickness, a reinforcing yellow mesh, a final layer of silicon, then creating mold seams (where the mold will separate) and spherical mold keys to lock the floppy silicon layer to the impending fiberglass layer. Each pooch has used about 2 gallons (20lbs) of Silicon so far.
Still a long carcenogenic way to go.
