About This

SEMI-PERMANENT MARINE SEALANT — REMOVABLE WHEN NEEDED — 4000 UV formula creates a strong, watertight seal that can be cleanly removed for future service, repair, or replacement. Choose this over permanent 5200 when you need to access through-hulls, hatches, portlights, or fittings down the road.
WATERTIGHT BOND — ABOVE & BELOW WATERLINE — Seals and bonds above or below the waterline with marine-grade adhesion. Waterproof and weather resistant through salt spray, sun, rain, and temperature extremes. Stays flexible without cracking or shrinking season after season.
UV RESISTANT — WON'T YELLOW OR CHALK — The 4000 UV formula resists ultraviolet degradation that breaks down standard sealants. White color stays white — no yellowing or chalking even after years of direct sun exposure on deck hardware and above-waterline joints.
BONDS FIBERGLASS, WOOD, METAL & MORE — Adheres to fiberglass, gelcoat, wood, aluminum, steel, and most marine plastics. Use for portlight bedding, small hardware mounting, hatch sealing, and on-the-water repairs where semi-permanent adhesion is preferred.
3 OZ TUBE WITH GLOVES — COMPARE TO 4200 — Compact 3 oz tube is perfect for targeted repairs, small bedding jobs, and keeping aboard for on-the-water fixes. Compare to 3M 4200 Fast Cure. Includes disposable gloves. By Berkland.
