Review: Works well; nice black coat; might need a few cans - I used this on the undercarriage of my 2015 jeep wrangler JK, after using another rust convertor previously as well. Months ago it was starting to look like a sad surface rusty state under there. The first thing I did was use a metal brush on all the rusty spots. Don't bother with spinning devices, etc, just use the long brush and some elbow grease. I then used a good rust convertor that converted the surface rust to a black finish on most of the metal. It went on with a paint brush. I probably could have stopped there, as it looked better already, but I wanted to take it another step with a protective coating. That's where this rubberized undercoating spray seems to have helped. I covered all the metal surfaces with this to provide a protective black coat. It sprays on as you would expect. Wear a resporator mask and eye protection at a minimum, and rubber gloves. Then get on down there and spray all your metal parts. I'm not sure I'd spray this on top of rust, but it would probably cosmetically cover it. I put it on the black converted rust. It gave it a, yes, "rubberized" black appearance to the surface. It is a matte finish with a slight dull rubberized reflectiveness. It isn't thick, but it does look to provide that extra protection. Note, I got a 2 pack, and that would be the bear minimum for my undercarriage. It's already mostly black on the frame and metal parts, so missed spots are less noticeable. I could probably use a 3rd can in good daylight with a bright light to see what I missed. 4 is probably too many though. Overall seems like good quality and smooth finish for undercarriage, more functional and less often seen. I'm not sure it would be as useful on a fully visible everyday surface though in terms of smooth looks. This stuff is super useful. I touched up a bunch of worn metal on some other outdoor stuff as well.
Review: Great Quality Spray Paint - Great deal on quality spray paint. I always trust Rust-Oleum and it was more convenient to be able to purchase on desertcart. Worked well and dried quickly. I just used it to touch up some paint in the engine compartment of my 1969 Dodge Dart. The texture was good. All that I could ask for in a rubberized spray paint.
