Rust-Oleum 344763 Automotive 2-in-1 Rust Reform & Seal, Quart, Black, 32 Fl Oz (Pack of 1)

This stuff is amazing. It dries quick to the touch and completely changed the undercarriage look of my Jeep. So far it is holding up well after a few washes and no new surface rust has shown through.

Stuff works great, was able to get a lot of my truck. I’d suggest getting two though.

This Rust-Oleum spray is a lifesaver! It works like magic to stop rust in its tracks and seals surfaces perfectly. The flat black finish looks great and blends seamlessly with automotive parts. Super easy to use, with excellent coverage. Highly recommend for anyone dealing with rust issues!

Pro: Product covered well, and you could tell from the smell that it was doing things differently than regular spray paint. Coating is a little bit rubbery, so it is what it says it is. Happy that it will prevent corrosion on my undercarriage. I lived in Colorado my whole life, then moved to Florida for school. it's been rough on my trucks frame,the combination of old road salts and the FL humidity. Am planning to undercoat my entire truck with it now, since this actually stops rust from continuing.Con: the can does not handle spraying upside down well, and it blows through propellant if held at any angle other than more or less vertically. The can still felt 70% full when it stopped spraying, so most of it went to waste on the one can I bought. Since I'll be putting it up on a lift later, I'll just finish spraying it then, where I can keep the can upright, but doing it in the driveway it ended up being wasteful.

Awesome

I purchased this product based on the great reputation that Rutoleum product have, this one is an exception, the paint itself is great, however, only when the spray can allows the paint to come out which is only the first 3 or 4 times that one presses the nozzle. After that you are stuck with an almost full can of wonderful paint that you can not use.I cleaned the nozzle with alcohol & pressurized air but even though the nozzle was clean & air went through the spray paint would not come out of the can. The paint seems to clog up inside of the can.

Paint sets easy and fast, used it on my rusted out Miata trunk, and would recommend sanding down the rusted bits to bear metal before application for added smoothness!

Living in Maine, with salt and sand on the road and winter snow, cars and trucks have a much shorter life. My 2005 Ford Escape started showing signs of underside surface rust, which was noted during vehicle inspection for registration. I was cautioned that the car might not make it through inspection, next time around. Unfortunate as the rest of the car's drive train and other systems are in excellent shape.The car was placed on jack stands, lightly wire brushed to get rid of the top coat of surface rust, then sprayed with Rust-Oleum 2-In-1 Rust Reform & Seal Spray. It was easy to apply and coated uniformly, leaving a black finish. I kept thinking rust would soon break through again, but that did not happen.The treatment will keep my car on the road at least a several more years, the metal surfaces are now protected and it looks a lot better with surface rusting stopped.
