(71-05205)","description":"\u003cp\u003e3M 5200 is the marine industry's benchmark polyurethane adhesive sealant — trusted for permanent, watertight bonds above and below the waterline. The 3 oz. tube format is ideal for targeted repairs, seam sealing, and through-hull fitting installations where a full cartridge would be excessive. Black colour suits dark hull applications, teak decking, and anywhere a neutral or white bead would be visually out of place.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePermanent polyurethane bond — extremely high strength above and below the waterline\u003c\/li\u003e\n\u003cli\u003eStays flexible after cure — absorbs vibration and hull movement without cracking\u003c\/li\u003e\n\u003cli\u003eTack-free in 48 hours; full cure in 5–7 days with no shrinkage\u003c\/li\u003e\n\u003cli\u003e4-hour working window after application for repositioning and tooling\u003c\/li\u003e\n\u003cli\u003eWon't sag or flow in vertical or overhead seams\u003c\/li\u003e\n\u003cli\u003eBonds fiberglass-to-fiberglass, wood-to-fiberglass, and most marine substrates\u003c\/li\u003e\n\u003cli\u003eApplies with a standard manual caulking gun\u003c\/li\u003e\n\u003cli\u003eColour: Black | Size: 3 oz. tube | SKU: 71-05205\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFiberglass deck-to-hull bonding\u003c\/li\u003e\n\u003cli\u003eThrough-hull fittings and transducer installations\u003c\/li\u003e\n\u003cli\u003ePortlight and hatch frame sealing\u003c\/li\u003e\n\u003cli\u003eTeak and wood-to-fiberglass deck seams\u003c\/li\u003e\n\u003cli\u003eKeel bolt and hardware bedding (permanent installations)\u003c\/li\u003e\n\u003cli\u003eBelow-waterline seam sealing on fiberglass hulls\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e Reach for 5200 when the bond needs to be permanent — through-hull fittings, deck hardware that will never be removed, and hull-to-deck joints.
