Graphite Powder

Mixed with epoxy to make a smooth, tough, low-friction coating. It's sanded to a slick but scratch resistant finish and left unpainted. Usually applied below the waterline. 2 oz bottle and 12 oz cans. 

Also one of the active ingredients in our Rubstrip Kit.  You have to mix it really thick to get the effect you want---about 1:1 by volume of graphite powder and epoxy.

Note: 6oz cans are no longer available from West System.
