CorrosionX Heavy Duty

( 0 Reviews )


CorrosionX® Heavy Duty (also widely known as CorrosionX HD) is a high performance thick-film version of CorrosionX. It was developed specifically to provide maximum protection against moisture intrusion and the resulting rust and corrosion. CorrosionX Heavy Duty is dripless and resists displacement or removal by splash, rain, seawater or even pressure washing. It is ideal for long-term protection against serious rust and corrosion assault and in situations where the surface being protected is exposed directly to the elements.

Unlike wax-based corrosion inhibitor barrier coatings, CorrosionX HD will not dry, harden or crack. The coating is self-healing and will slowly penetrate existing rust and corrosion, displacing moisture and corrosion-causing electrolytes.

For those really tough jobs where you need the ultimate protection against moisture, the answer is CorrosionX Heavy Duty. There is no other product like it on the market today. Pretreat fittings for easy dismantling even years later! Recommended for use on boat trailers by Field and Stream magazine.


Whatever the application – marine, auto, trailer, agricultural, industrial – CorrosionX Heavy Duty is the best you can buy! Here are two case studies that demonstrate the product's powerful abilities:

Case #1

Situation: A swing bridge in Sergeant, Texas, operated by the Texas Department of Transportation, that requires two 5/8" x 600' cables to open and close. Problem: Approximately 200' of cable is submerged under saltwater when the bridge is closed. Rapid deterioration of the cables required replacement every 57 days on average. Solution: Since the test cable had already been in use two weeks and rust was evident, the entire cable was first treated with CorrosionX prior to applying CorrosionX Heavy Duty. Results: The cable lasted 132 days, and when is was replaced it was due to normal fatigue — not because of rust.

Case #2

Situation: Diesel Fuel Filtering, an Alameda, CA based company is in the business of filtering and purifying diesel fuel for boats at anchor. Problem: It operates a 26' boat transported on a tandem-axle trailer. Both boat and trailer are in and out of saltwater on a daily basis, resulting in severe rust and corrosion of the trailer. Problems with electrical systems were common as saltwater attacked terminals and connections. Solution: CorrosionX Heavy Duty was applied to springs, electrical connections, winch and other areas on the trailer susceptible to corrosion. Results: Mr. Robert Sherman, owner of the company, wrote: "CorrosionX Heavy Duty was applied about two months ago and, as of this date, the barrier coat is still visible and apparently stopping further saltwater corrosion. A welcomed side benefit is the lubricating property – the trailer springs no longer squeak."
