Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

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.

Who should consider this sealant

  • Boat owners performing routine hatch and deck seal repairs.
  • Marine technicians addressing hull seams, trim, and cockpit joints.
  • Automotive enthusiasts sealing weather-prone gaps around windshields, gaskets, and body panels.
  • Home and workshop DIYers tackling moisture barriers in outdoor or damp environments.

Why choose Seachoice for your sealing needs

  • Reliable, flexible silicone formulation designed for auto and marine environments.
  • White color option that complements a variety of surfaces without drawing attention to the seam.
  • 10 fl oz tube provides ample coverage for both quick fixes and larger sealing projects.
