Today we sprayed tooling gel coat on the plugs for the bow and stern deck of the SUP.
This will form the molding surface of the mold. After the gel coat sets up, we will add layers of glass and resin to create a strong durable mold.
After the entire lamination is cured, we will separate it from the plug. The coating of PVA we sprayed on the plug prevents the mold from sticking. That is the theory.
But of course "past performance is no guarantee of future earnings."
