Tube, White\u003c\/h2\u003e\u003cp\u003eSudbury 320 is a single-component, fast-skinning marine sealant that cures to a clean white finish — the right choice for white hulls, gelcoat surfaces, and bright-finish hardware where color match is essential. It skins in approximately 10 minutes and reaches full cure in 1–7 days, forming a flexible, watertight bond that holds up above and below the waterline.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFast skin time: approximately 10 minutes\u003c\/li\u003e\n\u003cli\u003eFull cure: 1–7 days depending on temperature and humidity\u003c\/li\u003e\n\u003cli\u003eCures in temperatures from −29°C to +49°C (−20°F to +120°F)\u003c\/li\u003e\n\u003cli\u003eWhite finish — blends seamlessly with white hulls and gelcoat\u003c\/li\u003e\n\u003cli\u003eSuperior flexibility, elongation, and compression resistance\u003c\/li\u003e\n\u003cli\u003eExcellent adhesion to fiberglass, wood, metal, glass, Plexiglas, Lexan, and most plastics\u003c\/li\u003e\n\u003cli\u003eCan be wet-sanded or painted after full cure\u003c\/li\u003e\n\u003cli\u003eCleanup with mineral spirits\u003c\/li\u003e\n\u003cli\u003eNot recommended for wood deck seams\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHardware bedding on white or gelcoat hulls and decks\u003c\/li\u003e\n\u003cli\u003ePortlights, hatches, and trim on white-finish boats\u003c\/li\u003e\n\u003cli\u003eThrough-hull fittings on light-colored surfaces\u003c\/li\u003e\n\u003cli\u003eRubrail and fendering installation on white hulls\u003c\/li\u003e\n\u003cli\u003eGeneral marine hardware installation where a white, flexible, permanent bond is needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe 320 is the white-finish choice in the Sudbury 3 oz. tube lineup — best suited for white-hull boats where a black or clear bead would stand out. The tube format is ideal for smaller jobs, touch-ups, and tight spaces where a cartridge gun isn't practical.
