Once the fish mold is complete, the mold is laid open to expose both halves of the mold. A release agent is then added to the surface of the mold to allow the fish reproduced body to come out of the mold after glassing is set. We then brush in a thin layer of gelcoat followed by several layers of fiberglass.

A small block of wood is added to the backside of the fish mount so we can attach a hanger during the finishing stage. We then add a fiberglass paste to the edge of the mold and it is then clamped together. Once everything is hardened, the clamps are removed and the fish reproduction is removed from the mold. It is now ready for the Taxidermy finishing process.
