Heavy-Duty Corrosion Inhibitor Spray
Free returns on all eligible orders
You have 30 days to request a return. All sale items are final sale.
Protect electrical connections, terminals, and metal surfaces from the relentless effects of salt air, moisture, and marine corrosion. This heavy-duty corrosion inhibitor forms a flexible, corrosion-proof insulating film that bonds to metal surfaces and stays put — even under harsh offshore conditions.
Unlike rigid coatings that crack and flake over time, this formula remains pliable, maintaining a continuous protective barrier through temperature swings and vibration. Ideal for use throughout the season and as part of winterization and lay-up routines.
- Forms a corrosion-proof insulating film on contact
- Stays flexible — will not crack, craze, or peel
- Seals out salt air and moisture effectively
- Provides long-term protection under all weather conditions
- Safe for use on electrical connections, battery terminals, wire harnesses, and exposed metal
Parts Desk Insights
Best Use Case: Apply to battery terminals, electrical connectors, bilge pump wiring, and any exposed metal fittings prone to oxidation or salt spray exposure. Particularly effective as a final step after cleaning and inspecting electrical systems at the start and end of the boating season. A light coat on trailer hitch connections and winch cables also extends service life significantly.
