Formulated specifically for the harsh marine environment, providing a high-performance seal that resists salt water, UV rays, and extreme weather.
3M Marine Grade Silicone Sealant (PN08029) is the industry standard for above-the-waterline sealing applications. Unlike standard household silicones, this 304 mL cartridge contains a high-solids formula that bonds tenaciously to fiberglass, gelcoat, metal, and wood. It is specifically engineered to handle the high-vibration environment of boats and RVs, ensuring that your hatches, portholes, and deck hardware remain watertight for years. The sealant is mildew-resistant and can withstand temperatures ranging from -60°C to 232°C, making it reliable in both arctic and tropical conditions. Its easy-to-tool consistency allows for a professional, smooth bead every time, ensuring that your repairs look as good as they perform.
