POLYESTER SURFACING AGENT

Tack-free wax additive for no wax polyester resins and gel coats for a tack-free cure on the final coat. As the resin or gelcoat is curing, the surfacing agent rises to the surface and excludes the air from contacting the surface of the curing resin, creating a hard, tack-free cure. Waxed resin must be sanded for secondary bonding. 4 fl. oz. of surfacing agent per gallon of resin is required. See About Polyester Resins on the Polyester Resins page.
