About This

PERMANENT WATERTIGHT SEAL — ABOVE & BELOW WATERLINE — 5200 fast-cure formula creates a permanent, flexible bond that holds against water pressure, hull flexing, and wave impact. Use above or below the waterline for through-hulls, transducers, struts, and hull-to-deck joints.
24-HOUR FAST CURE — Skins in 1 hour, reaches handling strength by 24 hours. Traditional 5200 takes up to 7 days — this fast-cure version gets your boat back on the water sooner without sacrificing bond strength.
UV & WEATHER RESISTANT — Engineered for full sun, salt spray, and temperature extremes. Will not crack, shrink, or chalk after years of UV exposure. Maintains adhesion and flexibility season after season.
BONDS FIBERGLASS, WOOD, GELCOAT & METAL — Adheres to virtually every material found on a boat: fiberglass, wood, aluminum, steel, gelcoat, and most plastics. Also used for marine hardware mounting, portlight bedding, deck fitting installation, and boat carpet or marine flooring adhesion.
