Rust-Oleum Professional High Performance Clean Metal Primer in Flat White creates a rust-resistant foundation for a durable enamel finish. This oil-based, 400 VOC formula is designed for bare, lightly rusted or previously painted metal, helping improve topcoat adhesion and corrosion protection on indoor and outdoor projects. The 1-gallon container can be applied with a brush, roller or suitable spray equipment to clean, dry, properly prepared surfaces. Remove loose rust and flaking paint and lightly sand glossy areas before priming. Finish with a compatible Rust-Oleum Professional enamel for maximum performance, following the label for drying and recoating times. Clean application tools with mineral spirits. Not intended for galvanized steel or surfaces exposed to continuous water immersion.
