Description and Use
Automotive High Heat Primer (Spray) bonds to bare metal and helps create a smooth surface for top coat application. It is formulated to prevent rust and is recommended for use on automotive engines and other automotive surfaces which reach intermittent temperatures up to 2000°F (1093°C). For maximum protection, top coat with Rust-Oleum High Heat Paint. High Heat Primer features an advanced spray system that allows you to spray at any angle, even upside down for those hard to reach areas. A comfort spray tip with a wider finger pad reduces fatigue caused by continuous spraying.
Surface Preparation
Wash the surface with a commercial detergent, or other suitable cleaning method. Rinse with fresh water and dry with a clean cloth. Remove loose paint and rust with a wire brush or sandpaper until the metal surface is completely bare. Lightly sand smooth and glossy surfaces.
