Polyester Resin Wax Additive
How much hardener do you add to the polyester resin?
Report. The ratio of catalyst to resin is between 1 and 2% of hardener based on the total volume of resin to be used. For example, four drops of hardener make up 1% of 1 ounce of resin. The addition of more or less catalyst accelerates or slows down the hardening time of the resin.

Do you need gelcoat wax?
