Fiberglass Supply Depot Wax Additive is a 4 oz liquid surfacing agent designed to be mixed into the final gelcoat or polyester resin coat. It creates a tack-free, fully cured surface by migrating wax to the top layer, blocking oxygen and enabling easy sanding and polishing. Ideal for marine and composite projects, it requires precise dosing (4 oz per gallon) and must be used with MEKP catalyst. This additive streamlines finishing, reduces defects, and delivers professional-grade results every time.

Worked Perfect.
Good product for working with fiberglass. It works well when blended together with polyester resin or gel coat to cure it to a non sticky texture. I used it when I refinished the fuel tank area in my Champion DCX 221 Elite bass boat.

Improved Packaging
Yes, off gassing made me nervous but in the three years since the below review, they have significantly improved their packaging - sealed bag and even the can has a metal seal under the screw top that you have to cut open —>. “ If you can't seal dangerous liquids, don't try and sell them. This has never been opened, not even the plastic. I can tell that there's about half of a jar remaining by feel. And you better believe it stinks up anywhere it lives for a 25 ft radius.

Needed for non waxed gel coat-worked great!
Make sure you’re adding the right amount for your project. Keep stirring for to keep wax in the mix.
