Seachoice Auto/Marine Sealant 10 fl. oz.

Meet Seachoice Auto/Marine Sealant 10 fl oz — a white, one-component silicone sealant engineered for demanding automotive and marine sealing tasks. Housed in a convenient 10 oz tube, this ready-to-use sealant delivers a durable, flexible seal that resists water intrusion while accommodating movement across hulls, decks, engines, and transitions.

Why this sealant stands out

• Single-component silicone for quick, hassle-free application with no mixing required for reliable performance.
• Excellent adhesion to common auto and marine substrates such as metal, fiberglass, glass, wood, and many plastics, helping you seal joints, gaps, and seams with confidence.
• Waterproof and flexible after cure, maintaining a seal as surfaces expand, contract, or flex in varying temperatures and exposure to sun, salt, and spray.
• White finish blends seamlessly with many boat and vehicle surfaces, providing a clean, professional look on decks, hatches, bulkheads, and trim.
• User-friendly packaging comes in a practical tube that makes controlled, bead-by-bead application simple for both small repairs and larger projects.

Ideal uses and practical applications

• Sealing around portholes, windows, and deck hardware to prevent leaks and drafts.
• Gasketing joints between hull components, bulkheads, and floor panels where movement occurs.
• Sealing engine compartments, bilge areas, and tool-laden storage bays where moisture protection is critical.
• Securing trim, moldings, and joint lines in boats, RVs, trailers, and other vehicle exteriors.

How to use

• Prepare the surface: clean and dry all areas to ensure optimal adhesion.
• Cut the nozzle to your desired bead size and load the tube into a caulk gun for steady application.
• Apply a continuous bead along the joint, then smooth with a damp finger or a finishing tool for a clean, professional seal.
• Allow the sealant to cure per product directions and environmental conditions before exposure to water or stress.
