West System 423 Graphite Powder is a fine black powder you stir into mixed 105 epoxy for a low-friction coating that resists scuffing. Epoxy and graphite is the classic coat for rudders and centerboards, low-load, low-speed bearing surfaces, and the bottoms of racing boats that are dry sailed.
How much to add
Add about 10% by volume, roughly 1½ tablespoons per 8 fl oz of mixed epoxy. One 12 oz can modifies about one gallon of mixed epoxy. The coating cures black. It is not an antifouling: a boat that stays in the water still needs bottom paint.

- 423: 12 oz (340 g) can
