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 (about 4 oz per gallon) and must be used with MEKP catalyst. This additive enhances finish quality, reduces cleanup time, and is trusted by professionals for a smooth, durable surface.

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.

Way to expensive but needed

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
