Just throwing this out there as helpful insight for those who may be considering using this as a rust proofing, as they may be interested in knowing a real solution as this product imo acts more as a bandaid, and in some cases exacerbates an existing problem. In the case of a new car or car with no existing rust that your looking to protect from rust, I'd recommend a seasonal application of "fluid film". If your have existing rust I recommend the following, though it is involved, it's nothing difficult, only time consuming. Remove any large rust areas with a wire brush/wheel etc. Treat the area with "ospho" or a similar, it converts the iron oxide to iron phosphate turning the rust a dark gray black color and etching any exposed metal. Clean and dry. Paint with "por15" or equivalent. Then after the paint is dry seasonally apply fluid film to the entire chassis/undercarriage. Say goodbye to rust for good 👍

Juts be careful with some stock exhausts and aftermarket exhausts that have drain holes and some undercarriages also have drain holes, too. Coating over these may result in rot as water doesn't properly drain.

FYI, this stuff is the thin, cheap variety of "undercoating", and is more like flat black paint than anything else. I got a can of it as a filler for an order awhile ago, and it really is barely distinguishable from black paint. It splatters a tiny bit of texture, but it's uneven and so you get some thick spots and the rest is thin flat black paint.

I would STRONGLY recommend against using this, especially on a vehicle. And I usually like Rust-oleum products. I'm not sure why they make something so bad and why it hasn't been improved.


If you want the thicker stuff that is more like actual undercoating, you'll have to pony up for the "professional" version:

This stuff looks ok. Might use some under the old jeep if it's thick enough.

Well no but I suppose if you pulled your seats and carpet and sprayed maybe a gallon of it? That would. You'd be much better getting soundproofing mat though and installing that under the carpet.

If you cleaned underneath your tundra super well you could use it on the frame to both protect and make it look blacker. But there's some odds your frame already has protective coating on it.

That sounds like a lot even for a limo. I have never used more than 1.5 cans on a suv so i want to say 2 cans should be all you need.
