Tack Free Additive
Tack Free Additive (or some call it wax) ensures the final coat of resin and gel coat hardens tack free. How it works is when mixed with your gel coat or resin it rises to the surface and blocks the surface from the oxygen thus allowing the resin or gel coat to dry tack free. Generally you would use 1oz per quart and 4oz per gallon. Once added mix well as additive continues to separate from gel coat/resin.
