Old Salem 1959 Hard Racing Copper Bronze is recommended for use in fresh water on racing hulls, sailboats, runabouts or cruisers. It is a non-antifouling hard racing finish that can be buffed to give a high-gloss, ultra smooth surface. It can be used in saltwater for small, dry sailed boats which are not left in the water. Suitable for use on fiberglass, wood and steel hulls. Excellent for use on trailered boats.
