New England Copper provides full season antifouling protection against barnacles, algae, and hydroids in salt and freshwater on boat bottoms only. Its ablative copolymer base renders a smooth finish with durability and abrasion resistance. New England Copper releases biocide by the exposure of paint film to the water. New England Copper can be applied over all types of properly prepared bottom paints (except aluminum). For use in low fouling and cold waters where the fouling challenge is low.
