Cartridge, Clear\u003c\/h2\u003e\u003cp\u003eSudbury 301 is a single-component, fast-skinning marine sealant in a standard 10 oz. caulk cartridge, curing to a clear, flexible finish. It’s the high-volume choice for larger sealing jobs where appearance matters and a colored bead would be visible — portlights, windows, and bright-finish hardware on any hull color. It skins in approximately 10 minutes and reaches full cure in 1–7 days, forming a durable, watertight bond 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\u003eClear finish — virtually invisible once cured, works on any hull color\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\u003eStandard 10 oz. cartridge — fits any standard caulk gun\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\u003ePortlights, windows, and hatches on any hull color where a clear seal is preferred\u003c\/li\u003e\n\u003cli\u003eContinuous runs on transparent or mixed-color deck hardware\u003c\/li\u003e\n\u003cli\u003eThrough-hull fittings and keel bolt seals on light or multi-color hulls\u003c\/li\u003e\n\u003cli\u003eCabin sole, interior trim, and hardware where aesthetics matter\u003c\/li\u003e\n\u003cli\u003eAny large-area sealing project requiring a flexible, permanent, invisible bond\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe 301 is the go-to clear sealant for larger jobs — best suited for portlights, window runs, and any continuous bead where you’d burn through a 3 oz. tube fast. The cartridge format works with any standard caulk gun and is the practical choice for production work or bigger repairs.
