Anti-fouling coating composition containing high amounts of zinc, and novel methods of applying melt compounded anti-fouling coating compositions to components by heat fusion techniques. The components that can be treated include fresh water or salt water exposed components that are prone to biomass and fouling buildup. The marine exposed components can include running gear components, such as but not limited to, propellers, rudders, struts, shafts, bow thrusters, boat hulls (fiberglass or metallic) and the like.
