WAX SOLUTION 5%
Commonly used in the final coat.
Add 5% Wax Solution/Air Dry to the unwaxed polyester resin, vinyl ester resin, or gel coat to make it non-tacky when dry. It contains paraffin wax suspended in styrene solvent. The wax rises to the surface as the material cures and seals the surface from oxygen.
Resin will only cure in the absence of oxygen so this is needed for the top layer. If it is not used the top layer may feel sticky.
