Fiberglass Supply Depot Wax Additive is a 4 oz surfacing agent designed to be mixed into the final gelcoat or polyester resin coat. It migrates to the surface during curing, creating an oxygen-blocking wax barrier that ensures a tack-free, fully cured, and sandable finish. Ideal for marine and composite applications, it requires precise dosing (4 oz per gallon) and must be used with MEKP catalyst. This additive streamlines finishing by preventing sticky surfaces and reducing cleanup time.

Makes gel, coat, dry and not sticky
This wax additive helped the Boat shine a bit more made the gel coat dry without a tacky filling. I recommend this product to be added to all gel coats. Whether they come with wax or not.

Really good
Used on last coat of gelcoat. Even with Duratech high gloss additive it still needed on last coat.

Necessary when using Gel Coat WITHOUT a wax additive in it.
Worked great! Good value, ensures your final coat is durable. Used for the final coat of white gel coat to ensure a clean, properly cured, non-tacky finish on a sailboat. If you plan to use an anti-slip silica, make sure to mix it in with the wax additive before adding MEK-P (the catalyst that hardens the gel coat). Follow manufacturers directions - the ratios provided are integral to the success of your gel coat project.

Product itself works great. Packaging could be better.
Works as intended for adding wax to gel coat. Bottle is kind of awkward to pour a small amount without making a mess. Maybe a dropper cap or syringe would be helpful

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.
