Rust-Oleum Stops Rust Primer Sprays provide a sound base for applying Stops Rust enamels on heavily rusted metal. Using primers promotes topcoat adhesion, helps prevent chipping, cracking, and peeling, and eliminates the need for multiple enamel finish coats. It features a comfort tip with a wider finger pad to reduce fatigue caused by continuous spraying and an any-angle tip, which allows you to spray at any angle. Not for use on galvanized steel.
