Sharkhide Aluminum Hull Protectant, quart: Sports & Outdoors. 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. 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. Note that Sharkhide® is not an anti-fouling bottom paint.
