Rust-Oleum Self Etching Primer is designed to prepare bare metal, aluminum and fiberglass surfaces to promote maximum adhesion and smoothness of the topcoat finish. Self Etching Primer is a rust preventive coating that etches and primes in one coat. Self Etching 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.

How to Apply Self Etching Primer Spray?

Suitable Conditions to Apply

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 surfaces that, when heated, exceed 200°F (93°C) or galvanized metal. Avoid spraying in very windy and dusty conditions. Cover surrounding area to protect from spray mist.

Make Your Surface Ideal

Thoroughly clean the area to be primed with mineral spirits to remove all oil, grease, wax and dirt. Allow the surface to dry thoroughly. Lightly sand the surface with #400 grit wet or dry sandpaper. Keep the sandpaper wet by soaking it in water while sanding. Wipe the sanded surface clean when finished.


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 2 or 3 thin coats and allow each coat to dry for 2 minutes before applying the next coat. Allow the final coat of Self Etching Primer to dry for a minimum of 3-4 hours before dry sanding, or 15 minutes before wet sanding with #400 grit sandpaper. Do not use near open flame.
