06026 Heavy Duty Corrosion Inhibitor, 10 Wt Oz

Absolutely glad I picked this for my toolbox. i use it at work where tools often get exposed to moisture, and it keeps everything from rusting nicely. it’s a good, handy product that does what it’s supposed to. i also like that it’s easy to apply and dries quickly. 🛠️ definitely a helpful item to have around, especially for keeping my gear in good shape after using it in damp conditions.

After several trials this is the best protectant I've found so far. All the others washed away after winter driving. Dries to a waxy yellowish film. You need a couple of cans for a typical car's suspension.

This works really well to coat and protect things from rusting . . . especially in a marine environment. The only 'downside' is that it does leave the surface coated with a waxy~greasy coating that is yellow/brownish in color. But, I guess you have to think that there's gotta be something there to keep the surface from getting exposed and, if necessary, it is possible to remove this with a degreaser or mineral spirits, etc.

Used it for undercoating my car and to be honest this stuff is just fantastic. It is highly inflammable so care should be taken not to spray it on hot parts.

This is THE stuff to undercoat your car with. I have a 2007 Explorer, that had light rusting in 2018 when I bought it; a yearly coating of this has fully arrested all rust, and the parts have developed a black patina that almost makes them look new. It dries hard. It does not damage rubber, like most wet products. It doesn't absorb dirt and make your car unworkable like fluid film. Only downsides are it's sticky when sprayed; wear junk clothes and a proper mask; it's not toxic but you don't want wax in your lungs. It does eventually crack if exposed to a lot of UV, but this only happened on my trailer hitch (which still has no rust). Has a amber color, so only good under car.
