It cures to a flexible, mildew-resistant seal that does not yellow over time, making it well suited for exposed topside and below-deck applications. The sealant comes in a 1\/10 gallon cartridge in clear finish and is applied with a standard caulk gun. Marine technicians, boat builders, and experienced tradespeople working on watercraft or dockside structures rely on this product where long-term flexibility and weather resistance are required.\u003c\/p\u003e\n\u003cp\u003eThis sealant is intended for marine and coastal construction applications where joints, seams, and penetrations are exposed to UV radiation, standing water, salt spray, and wide temperature cycles. Typical uses include sealing deck hardware, hatches, portlights, and through-hull fittings. It performs in both residential boating and commercial marine service environments. The clear formulation allows it to blend into a wide range of substrates without visible color contrast.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMarine-grade silicone formulation resistant to saltwater, UV exposure, and temperature cycling\u003c\/li\u003e\n  \u003cli\u003eMildew-resistant cure — suitable for wet, humid, and below-deck environments\u003c\/li\u003e\n  \u003cli\u003eNon-yellowing over time, maintaining a clean appearance on light-colored surfaces\u003c\/li\u003e\n  \u003cli\u003eRemains flexible after curing, accommodating joint movement without cracking\u003c\/li\u003e\n  \u003cli\u003ePackaged in a 1\/10 gallon cartridge compatible with standard caulk guns\u003c\/li\u003e\n  \u003cli\u003eClear finish blends with most substrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose marine-grade silicone sealant suitable for use on fiberglass, metal, glass, and painted surfaces commonly found in marine and coastal construction applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eApplication should be performed by a qualified marine technician or tradesperson familiar with sealant work. Surfaces must be clean, dry, and free of old sealant, grease, and oxidation before application. A standard caulk gun is required for dispensing from the cartridge format. Allow full cure time before exposing the joint to water or mechanical stress — do not rush cure by applying water or coatings over uncured sealant.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Size\u003c\/strong\u003e: 1\/10 gallon cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Clear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSealant Type\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication Environment\u003c\/strong\u003e: Marine grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.83 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051135080290\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000120477\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343151333682,"sku":"7000120477","price":594.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310531866.jpg?v=1782018242","url":"https:\/\/voomisupply.com\/products\/3m-7000120477-marine-grade-silicone-sealant-clear","provider":"Voomi Supply","version":"1.0","type":"link"}
