Micron CF (Copper Free) is a multi-season, copper free antifouling that uses Biolux Slime Blocking Technology to repel slime and Econea(tm) to combat zebra mussels and barnacles. Can be used on any power or sailboat, including aluminum hulls, and as a polishing antifouling, Micron CF will wear away to help reduce friction, improving fuel efficiency and reduce paint build-up.
