Key item features

  • Lasting Rust Shield: Forms a moisture-blocking dielectric barrier that molecularly bonds to metal surfaces, protecting trailers, marine gear, and tools in salt-heavy, humid environments.
  • Marine Lubrication: Delivers long-lasting, marine-grade lubrication that clings to metal and resists pressure, friction, and washout, ideal for locks, hinges, and marine components.
  • Deep Penetration: Industrial-strength penetrating oil frees rusted parts, releasing corrosion on frozen bolts, marine fittings, and seized engine parts where other products fail.
  • Electronic Protection: Safe on circuits, battery terminals, and sensors, forming a dielectric film rated over 39,000 volts that displaces moisture and prevents galvanic corrosion.
  • Navy Qualified: Qualified by the U.S. Navy under the Advanced Corrosion Preventive Compound military specification, protecting outboards, terminals, and powerheads with a self-healing film.
  • Advanced Technology: Combines Polar Bonding and Fluid Thin Film Coating (FTFC) technologies to create a self-healing, moisture-displacing barrier that bonds to metal and halts corrosion.
  • Multi-Purpose Formula: Acts fast to free frozen bolts, displace moisture, and protect metal parts from corrosion in saltwater and extreme environments, without VOCs.

remarkable product

I bought a case of corrosion X and had three cans would not spray and had to be returned and the quality could be a little better but the product is top notch! this is 1,000 times better than WD-40 in every way!

seasonal corrosion control

Have used Corrosion X for many years, best anti-corrosion spray I have found. Use it on Vehicle wheel studs in Winter, concrete J-Bolts over winter or anything else that will see harsh elements for months and I don't want to see any corrosion come spring. Also has worked great on all my boats.

this works great on battery cables. It doesn't leave that corrosion crap on my cables like other brands. Highly recommend
