Features

  • RELENTLESS RUST PROTECTION FOR ANY WEATHER: This self-healing barrier clings and protects metal through rain, seawater, and pressure washing; it wont drip, wash away, or quit, making it a reliable shield in even the harshest outdoor conditions.
  • BUILT TO PROTECT FOR YEARS, NOT MONTHS: From boat trailers to barn doors, this long-lasting formula keeps working for up to 5 years indoors and 2 years outside; perfect for anyone who needs reliable rust protection.
  • IDEAL FOR HEAVY-DUTY ELECTRICAL CONNECTIONS: Designed for larger terminals and connectors like battery posts and grounding lugs, this thick, non-conductive formula provides lasting protection without harming sensitive components, perfect where rugged sealing is needed.
  • STAYS FLEXIBLE, NEVER FLAKES OR CRACKS: Forget waxy sprays that dry out and break down, this rust shield flexes with your gear, staying active and bonded even when machinery shifts, vibrates, or takes a beating in the field.
  • SMART SCIENCE THAT BLOCKS HIDDEN DAMAGE: Polar Bonding locks onto surfaces to stop corrosion before it starts, preventing electrolysis and galvanic damage in places you cant even see, from engine bays to salty docksides.

Description

CorrosionX uses Polar Bonding technology that doesn’t just slow corrosion—it actually kills existing rust and stops it from spreading, providing long-term protection on any metal surface. It causes metals like steel or aluminum to behave like noble metals (gold, platinum), making them resistant to corrosion while preventing electrolysis between dissimilar metals. Absolutely. It’s MIL-PRF-81309H qualified, used by the U.S.Navy, ideal for industrial use

  • The Ultimate Protection Against Corrosion
Size: 12oz Aerosol
CorrosionX Corrosion Technologies 90104 Heavy Duty 12 oz. aerosol is an absolute lifesaver for anyone who owns a boat. I've been using this product to coat my boat motors monthly, and the results have been nothing short of amazing. When I first bought the boat, I noticed some salt corrosion starting to show, but after using CorrosionX, it fixed it right up and has kept my motors looking like new ever since. The aerosol application makes it incredibly easy to use, and the protective coating it provides is second to none. I no longer have to worry about saltwater corrosion damaging my motors, thanks to CorrosionX. Another great feature of this product is its versatility. It can be used on a variety of surfaces, including metal, rubber, and plastic, making it a must-have for any boat owner. Overall, I highly recommend CorrosionX Corrosion Technologies 90104 Heavy Duty aerosol to anyone looking to protect their boat from corrosion. It's a small investment that can save you a lot of money in the long run by preventing costly damage. ... show more

  • Expensive but worth the money
Size: 12oz Aerosol
Kind of expensive but worth the money. I use this on my boat trailer to help keep corrosion down on the leaf springs as well as the winch and around the axles. The stuff is really nasty and goopy but coats everything to protect from corrosion. Just be careful where you put it and make sure it's not going to be anywhere that you're going to touch generally speaking because it'll get all over your hands and clothes if you're not careful. It appears to last a long time however it does attract a lot of dirt so whatever you spray tends to look really nasty after a few months. ... show more

  • Salt Water Must-Have
Size: 12oz Aerosol
Corrosion-X is highly effective as a rust repair and protective agent and is required when you live or work on the salt water. It works by halting the oxidation process and providing a durable layer of protection. It lasts a long time, is easy to apply and doesn't require heavy sanding or prep work. It is a must-have for the maintenance and repair of rust-prone equipment. The only down side is it's sticky and will stain any clothing items it touches so be mindful of where you've sprayed it. Otherwise, it's our go-to for work on the water. This is our 5th purchase. ... show more

  • HD is really thick.
Size: 12oz Aerosol
Update: its Nov again and time to apply some more corrosion protection under the car and the CorrosionX HD I sprayed last year still seems to be on. Can see it still thick on the transmission pan and this area is under the car open and exposed. The inside of my snowblower also looks great no signs of rusting. Can still see the thick coating of the CorrosionX HD and the metal underneath looks clean like when I rebuilt it. Working on my car i noticed rust at alot of areas so decided to at least try to stop it. Came across CorrosionX and saw that the HD is the thickest stuff so it should stay on the longest and not get washed off. Well it really is some thick stuff. Sprays on thick with alot of bubbles. It does seem like over time the bubbles settle out. I sprayed it all over a new transmission pan i installed due to the original one rusting so bad. I also sprayed all over the cars subframe. Also sprayed down the inside of my snowblower transmission. Depending on how this stuff lasts over the winter I think next time I will try the XD version instead. The HD can is only 12 oz and its so thick I didnt seem to get alot of coverage from each can. I would use this stuff alot more if it wasnt so expensive. I cant even get it locally easily so it gets expensive ordering this stuff. ... show more
