The Rust-Oleum Corporation had its beginning in a fish-oil-based paint developed by Robert Fergusson, a former sea captain. Rust-Oleum Rusty Metal Primer Spray is designed to adhere to rust and drive out moisture and corrosion, providing a surface to which top coats of paint will adhere easily. You can use it indoors or out and it comes in spray or liquid versions. Applying it takes just a little preparation.
Things You'll Need
- Wire brush or steel wool
- Paint scraper
Clean the surface of rust, grease, oil and other substances, using soap and water. You can substitute household cleaner or trisodium phosphate (TSP) if you wish, but Rust-Oleum advises against cleaning with solvents, noting that they smear grease and grime around.
Chip off rust and loose paint with the paint scraper, wire brush and sandpaper. Lightly sand glossy surfaces.
Rinse the surface with water and let it dry thoroughly.
Shake the spray can vigorously. Do this for one minute after you hear the mixing ball begin rattling. Shake frequently while applying the primer.
Spray steadily back and forth, holding the can 10 to 16 inches from the surface, keeping the can in motion and slightly overlapping your strokes.
Apply two coats a few minutes apart. Let the primer dry thoroughly before applying a top coat.
