Based on a flexible polyurethane chemistry, it cures to a tough, resilient seal that holds above and below the waterline. It absorbs stress from shock, vibration, and the natural swelling and shrinking of hull materials, keeping bonds intact over time. The sealant remains workable for up to four hours after application, allowing positioning and tooling with a trowel or spatula. It will not sag or flow in vertical or horizontal seams once applied. Licensed marine technicians and experienced boat builders are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThis sealant is suited for a wide range of structural and sealing tasks on recreational and commercial vessels. Documented applications include fiberglass deck to fiberglass hull, wood to fiberglass substrates, porthole and deck fitting installation, motor mounting on fiberglass transoms, hull seams above and below the waterline, centerboard trunk joints, stern joints, strut-to-planking connections, and deck housing installations. It is applied with a standard manual caulking gun using the 1\/10 gallon cartridge format supplied in this SKU.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePermanent, high-strength bond that retains strength above and below the waterline\u003c\/li\u003e\n  \u003cli\u003eFlexible cure absorbs shock, vibration, and substrate movement without cracking\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to weathering and saltwater exposure\u003c\/li\u003e\n  \u003cli\u003eRemains workable for up to four hours after application for trowel or spatula finishing\u003c\/li\u003e\n  \u003cli\u003eNon-sag formula holds in vertical and horizontal seams without flowing\u003c\/li\u003e\n  \u003cli\u003eApplies with a standard manual caulking gun for controlled dispensing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for bonding and sealing fiberglass to fiberglass, wood to fiberglass, and related marine substrate combinations on boat hulls, decks, and structural fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by marine technicians or qualified boat builders.
