SHARKHIDE METAL PROTECTANT is a clear, tuff, flexible coating that protects metals (aluminum, steel, stainless, brass, copper and more) from the damaging effects of water, (both fresh and salt) acid rain, road spray, soot, and alkaline. Sharkhide is both UV stable and ozone resistant. SHARKHIDE is easily applied in a variety of methods such as wipe, spray, dip and brush, and it dries in seconds. In most cases, a single application can last many years. It can also be used to renew and protect old chalky painted and fiberglass finishes.
