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. 2 fl. oz. of surfacing agent
per gallon of resin is required. See About Polyester Resins
on the Polyester Resins page.
