3M Marine Grade Silicone Sealant, Clear - Available in 3 fl oz Tube and 10.3 fl oz Cartridge
3M Marine Grade Silicone Sealant is a moisture-curing, clear silicone sealant engineered for above-the-waterline sealing on interior and exterior boat surfaces. It bonds to bare and painted metal, fiberglass, glass, non-oily woods, many plastics, and abraded rubber, forming a flexible, water-resistant seal that resists yellowing and sagging even after years of sun and spray exposure. Use it to seal hardware, fittings, windows, hatches, trim, and other above-waterline joints where a clean, durable, paintable-clear finish is required.

Sizes & Options
This sealant is available in two package sizes to match the scope of your job. Choose the 3 fl oz Tube for small repairs, spot sealing, and touch-up work where a full cartridge would go to waste. Choose the 10.3 fl oz Cartridge for larger projects such as re-bedding hardware, sealing windows and hatches, or general above-waterline sealing runs, since it fits a standard caulking gun for controlled, continuous application. Both sizes use the same clear, moisture-curing formula, so pick based on the volume of sealant your project requires.
