This tutorial is about making molds with simple materials to make a fiberglass part.
It is difficult to get much accuracy with cardboard, but the better the mold, the better the part… so, we can get a good result.
Repairs can be made with body filler.
The mold release agent is a mixture of polyvinyl alcohol and hydrated ethyl alcohol (1:1).
What I mix with the resin is the catalyst/hardener that comes with it (as oriented by the manufacturer).
While working with fiberglass, always use equipments for individual safety.
