Thanks for sharing your experience. For best results using Rust-Oleum Stops Rust Clean Metal Spray Primer, remove all dirt, grease, oil, salt and chemical contaminants by washing the surface with a commercial detergent, or other suitable cleaning method. Rinse with fresh water and allow to thoroughly dry. Remove loose paint and rust with a wire brush or sandpaper. Previously coated surfaces must be sound and in good condition. Apply holding the can 10-16" from surface and spray in a steady back-and-forth motion, slightly overlapping each stroke. Keep the can the same distance from the surface, keeping it in motion while spraying. Apply two or more light coats a few minutes apart to avoid drips and runs. Holding the can too close to the surface or heavy application will cause the primer to run.
