Keep the aluminum hull on your pontoon or fishing boat looking great! A couple of quick-drying coats of Sharkhide can protect your boat from streaks, stains, water lines, and oxidation for years. Protects in fresh, brackish, and saltwater. Sharkhide is easily applied and requires no special maintenance. Works on new, polished, or acid-washed aluminum surfaces, as well as copper, brass, steel, and stainless. Sharkhide will not chip, peel, flake, or yellow - ever! One quart provides two coats on most fishing boats; two quarts provide two coats on pontoon boats with enough left over for touch ups. Note that Sharkhide is not an anti-fouling bottom paint. Shipped ground only.
