Fluid Film Black 11.75 oz Pack of 3 Rust Converter Spray with Rust Remover, Prevention, and Inhibitor Properties for Metal Protection and Undercoating. Includes Gloves, Nozzle & Bundle.

I use this on my jeep , and it works extremely well and doesn’t wash off .. the first time you use it it takes about 5 or 6 cans to do inside all the doors and every square inch underneath.. then after that ya just grab like 2 cans before every winter and touch up spots if need be .. excellent product ..

Very easy to use, great coverage. Two cans did my truck, will definitely buy again.

The listing doesn't really spell this out, but this rust converter does not dry like paint. 4 months after using it on the frame of an old truck and it's still tacky. Seems to be sticking to the frame though. If you are looking for a show quality finish this is not the product for that. If you just want to stop an old vehicle from rusting away this seems to be doing the job.

Covered all rust under my Tundra with 3 bottles. Looks and works great! Easy to use. Will use for the rest of my life.

Fluid Film Black Rust Converter Spray is a must-have for anyone dealing with metal corrosion issues. This pack of 3 offers excellent value. The spray not only removes rust but also prevents its return, making it an effective rust inhibitor. The included gloves and nozzle add to the convenience, making it a comprehensive solution for metal protection and undercoating needs. Highly recommended for its reliability and ease of use.

It’s horribly messy, never dries up. You might as well spray motor oil all over everything.

I am thrilled with how my undercarriage has turned out, I was honestly starting to worry about how I was going to stop very aggressive sea salt rust but this has done it, I have just a couple of spots that the three cans couldn't cover so I will get another batch and have some for future projects. if you need rust removal and prevention that's easy to apply then you have found a product worth your consideration, especially because it won't break the bank.

It’s never a good time when in the market for this type of product. But this stuff does the trick. Comes with all the stuff you need apart from the grinder and wire brushes your need to get to the point of using this product. But it does provide long tube hoses. So you can get down and into the frame rails. Keep in mind this doesn’t convert rust into solid metal. You're likely to reveal parts that could likely be rust all the way thru. Remove as much rust as you can with a wire brush and brush on drill and grinder. Before apply this stuff. You can spray over top of rust it hopes it’s gonna convert it underneath. Rust will continue to eat. And it will eat thru any paint applied it no time at all. This stuff has a great finish black to it. But you want to make it look real good steel it over top for a dope finish. But this kit is still an amazing product applies good. Goes on thick. You will need a couple kits if your looking to do the whole underneath
