With the propousal of making a urethane copy of the master, we built a "glove" type mold. This mold consist on applying several silicone coats along the master surfaces untill forming a overlayed sking of 7/8 mm thick. That silicone "glove" will be then wrapped on a divided in sections bondo mother. This kind of mold is the perfect mate for a rotocasting job.

First of all we placed the master in a stable and fixed position, using a long stick screwed inside the model. Then cleaned the whole master with the airgun with enough pressure to ensure a completely clean surface. Once clean, mixed the first silicone to apply. We waited around 30 minutes after mixing, this way the silicone wouldnt be completely liquid and would be easier to apply to vertical surfaces. The most critical layer is the fist one, because it will transfer the surface to the copy, so it needs extra attention to cover all the surface to replicate with a thinn and homogeneous silicone film.
