PVA is the backup layer that gets the part off the mold. It sprays or brushes on as a liquid and dries to a smooth water-soluble film between the mold and the layup, so even a gree n mold or a marginal wax job releases. It also seals the gelcoat surface from air, which is why it promotes a full cure on polyester gelcoat instead of a tacky one. Water-soluble parting film, washes off the part with water 8 fl oz covers approximately 20 sq ft Best applied by spray; a soft bristle brush also works Spray with a small orifice gun at 90 to 100 psi, or use an aerosol Promotes complete cure of polyester gelcoat Lay it over wax, not instead of wax, on tooling you care about.
