However, badly rusted metal areas need more prep work and possibly a special primer. Start with a wire brush (Photo 1). Scrub partially rusted metal areas with a wire brush to remove flakes and powdery surface rust, then prime with a rust-inhibitive primer. Once done, you can paint over rust.
Before you can begin priming and painting your project, you'll need to remove all of the rust and begin with a clean slate. If you don't, your new paint job will have an uneven surface and risk peeling. Effective tools to use on rusted metal include wire brushes and sandpaper.
