Rust-Oleum 248658 Stops Rust Reformer Spray Paint, 10.25 oz, Matte Black by Rust-Oleum

I absolutely love using Rust-Oleum Rust Reformer Spray — especially this 6-pack, which is perfect for regular use. I’ve used it on everything from automotive frames to outdoor metal fixtures, and it consistently performs. It’s my go-to for converting rust into a paintable surface without the need for grinding or sanding down to bare metal.

The spray goes on evenly and dries to a solid black protective layer, creating an ideal base for topcoats like enamel, primer, or bedliner. It bonds well and helps prevent rust from bleeding through, even on surfaces that were heavily oxidized.

The product has no strong odor, and the spray nozzle delivers a consistent, controlled application. Whether you’re a DIYer or doing more industrial projects, this is a high-performing and affordable solution that saves time and effort.

Q&A:

Q: Does this actually convert rust or just cover it?
A: It chemically converts rust into a stable surface, allowing you to paint directly over it.

Q: Can it be used under Raptor bedliner or topcoats?
A: Yes — it’s ideal as a base layer under topcoats, including Raptor, enamel, or epoxy finishes.

Q: Does the black color bleed through light-colored topcoats?
A: Not usually, but using a light primer over it before painting will ensure full color coverage.

Q: How long does it take to dry?
A: Typically 15-30 minutes to touch and 24 hours for full cure before applying topcoat.

Q: How many square feet does one can cover?
A: Each 10.25 oz can covers about 8–10 sq. ft, depending on surface texture and rust depth.

I bought this because I had light rust beginning to appear on one of my exterior wheel wells. I followed instructions, lightly sanded area, washed with soap and water rinsed let dry and then applied light coats. two to three. from a foot distance.
I usually do an average job at things, but this one I can proudly say turned out excellent!
Ease of use!!! It applies real easily! Nice finish!!! Didn’t even have to paint, since it resembles the color of my car. I don’t want to invest more money on a car that is aging so this fits the bill! I hope rust stays away, or is at least delayed before I retire!!!

Excellent product. Sprays upside down even. strong pressure, even spray. Excellent coverage, good rust primer, just lightly brush off loose rust and spray with a household cleaner like Spray nine, hose off, dry then paint with primer. it is enamel base so if you spray another enamel top coat you can do that in less than the 24 hrs they say. I waited 4 hours on a hot day and top coated it.

Works great. Cleaned area with wire brush then sprayed area. Later tested by lightly removing black pain and only found clean metal with no rust so it works because I didn’t find any rust. It’s not just covering but actually removing
the rust.

I’ve dealt with rust on my truck’s undercarriage and outdoor tools for years, and this Rust-Oleum Stops Rust Reformer spray has been a total game-changer. Instead of the usual sanding and scraping, I just cleaned the rusty spots and sprayed this on. The rust actually transforms into a solid, paintable surface — no more flaky mess!

The flat black finish looks clean and professional, and it’s held up great through rain, mud, and even winter salt. I love that it dries fairly quickly and doesn’t run or drip if you’re careful with your spray technique.

What impressed me most is how durable it feels. Months later, there’s no peeling or new rust creeping in. For anyone tired of fighting rust the hard way, this spray is a simple, effective solution that really delivers.
