CorrosionX HD Heavy Duty Corrosion Inhibitor - 12 oz Aerosol (90104)

CorrosionX HD (Heavy Duty) is the thicker version of CorrosionX, made for metal that lives out in the weather. It goes on as a dripless film that stands up to rain, salt spray and even pressure washing, and it never dries, hardens or cracks like wax-based coatings. Over time it creeps into existing rust and pushes out moisture.

Why boaters use it

• Long-term protection for metal exposed to salt water and weather
• Dripless film that resists washout
• Will not dry, harden or crack
• Self-healing: the film flows back over scratches
• Stops galvanic corrosion between different metals
• Pre-treat fittings and fasteners so they come apart years later

Where to use it

Boat trailers (springs, axles, brake parts, winch), outboard brackets and steering, anchor and deck hardware, engine exteriors, stored tools and equipment.

Good to know

For electronics, tight threads and moving parts that need a thin, penetrating film, use regular CorrosionX (CorrosionX 6 oz or CorrosionX 16 oz).
