CorrosionXHeavy Duty Rust Prevention Spray, 3-Pack of 12 oz Cans, Waterproof Anti-Corrosion Coating for Metal Protection with Long-Lasting Durability

Good for preserving undercarriage vehicles

I love this stuff, I take a box to my mechanic every year and have him spray the underside of my Jeep. Up here in maine the salt and snow is bad. Corrosion X does an amazing job. 10 years and no rust on my Jeep. My mechanic has started spraying corrosion x on his vehicles.

As advertised

This is an excellent product but only if you actually received what you paid for. I purchased the HD green can but received the regular red can. Would have given it 5 stars if I had received the correct product.

I love all the products they make. This is ALOT thicker and offers long protection and doesn’t distort rubber seals

You can never have enough protection from corrosion in the saltwater environment . Corrosion X HD is the best of the best !Captain Kevin FaulknerF/V NOTORIOUS

tested it by soaking a big sponge with the extended version then wiped down the sides of my 26' aluminum boat.6 months later the water beaded off. Saltwater will not affect it at all. Getting a new boat trailer with a new aluminum boat, and will soak anything and everything on the trailer that's bolted, SS or galvanized. IT WON'T MATTER!

I use this outdoors.tractor trailer electrical plugs.winter salt and calcium applications corrode contacts quick.1 quick squirt does it.always reconnecting plugs lube stays put. Reapply every 60 days and your plugs will not corrode.if already corroded it stops it dead 1 can will do about 100 applications.have been using for years.best product I have ever tried.
