This environmentally-friendly, citrus-based polish deep cleans and protects your hull so it’s always in racing condition. Its long-lasting, high-gloss finish repels water to reduce drag for ultra-fast results. McLube Hullkote™ applies easily over other waxes and polishes and is safe to use on fiberglass, metal, plexiglass and painted surfaces. Hullkote™ lasts more than a season when applied above the waterline, and more than 20 hard days of sailing when applied below.
