DESCRIPTION AND USES
Rust-Oleum Automotive Engine Primer 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 500°F (260°C). For maximum protection, top coat with Rust-Oleum Engine Enamel. Engine 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.
PRODUCT APPLICATION
READ ALL INSTRUCTIONS CAREFULLY BEFORE STARTING PROJECT
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.
APPLICATION
Use outdoors or in a well-ventilated area such as an open garage. Use when temperature is between 50-90°F (10-32°C) and humidity is below 85% to ensure proper drying. Do not apply to galvanized metal. Do not use on metal directly exposed to flames. Avoid spraying in very windy and dusty conditions. Cover surrounding area to protect from spray mist.
Shake can vigorously for one minute after the mixing ball begins to rattle. If mixing ball fails to rattle DO NOT STRIKE CAN. Contact Rust-Oleum. Shake often during use. Hold can 12-16" from surface and spray in a steady back-and-forth motion, slightly overlapping each stroke. Keep the can the same distance from the surface and in motion while spraying. For best adhesion, apply ONE thin coat. Do not apply a heavy coat or multiple coats of Auto Plastic Primer. Do not use near open flame.
DRY & RECOAT
Dry and recoat times are based on 70-80°F (21-27°C) and 50% relative humidity. Allow more time at cooler temperatures. Dries to the touch in 20 minutes and dries to handle in 1 hour. Apply a second coat or top coat within 1 hour or after 48 hours.
CLEAN-UP
