CRC 06026 Heavy Duty Corrosion Inhibitor, 10 Wt Oz

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.

Excellent product. I purchased this to rust proof my jeep during the salty winters of Pennsylvania, and this product seems to protect the best, and it lasts the longest; all at a very competitive price to the alternatives. It goes on pretty thick and can be a sticky mess when applying, so best to apply outside. Also, it has a noxious odor, so be sure to use a respirator when applying. The odor dissipates after a couple days.

This stuff is incredible. Have a powder coated black running board on the truck, and wanted something to keep the salt road spray from getting in the crevices. This dries matte, doesn't get tacky or sticky, and goes on very well. You could look at the end result and never even notice it was coated, and there's no greasy residue like with fluid film. Not the greatest coverage per can, and the sprayer gets kind of gunky after a while. But dries very nicely and evenly.For coverage on fluid film on a truck frame, I'd use about 8-10 cans of fluid film. With this, I would plan on getting 10-12 cans. But the durability is outstanding. Really a good product.

This CRC is a great product I have used on at least 4 vehicles. The only complaint is that every once in every half dozen cans, I get one that just squirts out everywhere onto the can, my hands and onto the floor as I spray. Yes, I align the nozzle with the black dot...This last can did just that...

Excellent rust preventative for slowing down development of future rust in northern climates that salt roads. Best used on vehicles purchased with little rust from southern states that are transported to north before their first winter but still excellent for slowing down progession. Use once per year in fall before first snow fall. 3 cans is sufficient for most vehicles.

Heavy duty, but can also be sprayed on a cloth and wiped on for less product overspray

Keeps out rust . Easy to spray. Good price

Skip the fluid film mess. This is the rust inhibitor you want. Dries and lasts much longer.
