Rated 4.5 out of 5 stars.
This is a 6-pack of the classic Rust-Oleum Rust Reformer.
Each can is 10.25 ounces, and it's flat black.
The magic of this stuff is that you spray it directly over rust, and it chemically converts it into a protective, primer-like barrier.

No need for extensive sanding or prepping.

Just spray it on and it stops rust in its tracks while prepping the surface for a top coat.

It's a staple for any garage or workshop.

This bundle includes six cans, so you'll have plenty for multiple projects.
