Transform heavily-rusted metal into a paintable surface with Rust-Oleum Stops Rust Rusty Metal Primer. This primer bonds tightly to rust and forms a surface top coats can adhere to-while driving out the corrosive air and moisture other primers leave behind. For best results, apply two or more light coats a few minutes apart. | Rust-Oleum Stops Rust Rusty Metal Primer Spray Paint in Brown | Size 12 oz
