Rust-Oleum 248658-6PK Rust Reformer Spray, 10.25 oz, Black, 6 Pack

Always a good choice and seems to work, will update once it’s been awhile to see how it lasts. Seems to go on smooth and leaves a decent finish. Stays dark and doesn’t lighten with makes it easy to blend and not look rough. Sticks just fine with minimum running

10/10 product! Worked great after throwing on some ospho on my 2005 Chevy 2500HD frame then applying this as a base coat. Was very surprised on how good it came out especially due to me not having much experience with spray paint. I will say I wish the nozzle was a little bit better in a way to spread out the paint more but overall I had a great experience with this product and plan on using this more in the future!!!

Decided to refinish an old safe with the rattle cans and surprisingly they did a good job. Prepped as usual and top coated as directed and it came out good. May try their product on our old work truck for the fun of it.

This works great when doing body work

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.
