How to Apply Engine Primer Paint Spray?

Ideal Environmental Conditions

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.

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.


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.
