Cosmoline RP-342 Black Rust Preventive Spray (Military-Grade) 6-Cans

I'm a pickup truck guy, and I undercoat every pickup truck I have. Typically I use a lanolin type coating, but tge lanolin doesn't last long. However this stuff, you can quickly see why it is military grade. Thus stuff coats quickly, easily, and we'll. Better yet, this stuff has staying power, it looks and feels like a crayon type wax. One recommendation, invest in a tyvek suit. Thus stuff will get on you, and it takes a lot of effort to get it off.

I wish it didn’t smell, but it is Cosmo. product works. Great coverage awesome!!!

Put it on my truck after buying new and still going strong after a year.

I wire brushed what I could, and applied over all surface rusted areas, and used woolwax with the pro gun to spray inside the frame rails and areas I couldn't get with these cans.The application process is messy for sure. Wear a cap, face shield, respirator, coveralls, and gloves if you don't wanna have it all over you. After it's cured, it isn't too messy to work on the vehicle. It drys to a hard waxy finish and will transfer a little bit if you rub against it, but nothing like grease. Doesn't smell much at all after a few days either. First couple days it had a typical waxy cosmoline smell. I would definitely recommend it for delaying corrosion. Since it's waxy, it won't flake off and trap water like paint can if it fails. I needed about 5 cans for my 04 Tacoma regular cab.

This stuff looks good and works well

Goes on smooth and easy, gets good coverage as I used about 3.5 cans on a truck. Remains slightly tacky even after drying.

The product viscosity is more thin than anticipated but it works very warm. Actually easier than I expected due to the material spraying thinner. Easy to get good coverage. Would highly recommend product and seller.
