CRC Heavy Duty Corrosion Inhibitor Spray — 10 oz 4‑Pack, Long‑Lasting Non‑Conductive Moisture Barrier

CRC 06026 Heavy Duty Corrosion Inhibitor is a long-lasting, flexible spray that protects metal parts, electrical connections and fasteners from salt spray and high humidity.

Designed for marine and industrial environments, this 10-ounce aerosol formula from CRC forms a thin, resilient film that repels moisture and slows corrosion on exposed metal surfaces. Supplied as a 4-pack, it’s convenient for keeping multiple vessels, vehicles or equipment sets protected and stocked. Use it wherever salt, spray or persistent humidity threaten electronics, steering linkages, shafts, spindles or stored machinery.

How does this inhibitor protect electronics and electrical connections?

The formula leaves a non-conductive, flexible barrier that excludes moisture while maintaining contact integrity. It reduces the risk of corrosion-driven failures on terminals, motor brushes and connectors without interfering with electrical performance.

• Non-conductive coating prevents shorts and tracking
• Displaces moisture from connectors and switches
• Safe for use on battery terminals, wiring harnesses and circuit contacts

Can I use it on mechanical parts like steering and throttle linkages?

Yes — CRC’s corrosion inhibitor is formulated to cling to moving parts and provide long-term protection without gumming or impairing movement. It helps preserve linkages, spindles and shafts exposed to salt-laden air.

• Flexible film resists cracking when parts move
• Protects fasteners, pivots and exposed bearings
• Works on metals commonly found in marine hardware

What surfaces and applications is this spray best suited for?

This product is versatile across many applications: from small electrical contacts to larger engine components and stored equipment. It’s particularly valuable for any metal parts regularly exposed to salt spray, coastal humidity or storage conditions that promote corrosion.

• Electrical connections, terminals and motors
• Engine components, fasteners and exposed hardware
• Shafts, spindles, steering and throttle linkages

How do I apply the spray for best results?

Shake the aerosol, hold the can upright, and spray a light, even coat onto clean, dry surfaces. Reapply periodically or after heavy exposure; for long-term storage, coat parts thoroughly and wipe away excess.

• Clean surface of oil, grime and loose rust first
• Apply thin, even coats and allow to dry between passes
• Touch up high-exposure areas after storms or prolonged salt contact

Who is this product for? CRC 06026 Heavy Duty Corrosion Inhibitor is aimed at boat owners, marina technicians, fleet managers, mechanics and anyone maintaining equipment in coastal or humid environments. It’s also useful for homeowners storing metal tools or parts, and for industrial maintenance crews needing reliable corrosion control. The 4-pack format suits professionals who service multiple units or individuals who want spare cans for seasonal maintenance and quick touch-ups.
