TotalBoat Black Colored Gelcoat with Wax – Air Dry Marine Gel Coat for Boat Hulls, Repairs and Composite Finishes (Gallon)

One gallon was enough to cover 360 Sq Ft deck. 24 years ago I used same top coat product so I hope this time it will last another 24 years of foot traffic on the deck.

vague instructions on mix ratio with will cause the gelcoat not to harden if the right proportions aren't used. Followed sanding process and applied 5 coats but still went through the coat to the fiberglass. Tech support was not that helpful.
