RCM Acid Metal Etch Primer

RCM Metal Etch Primer is a high-performance water-based primer specially designed to provide exceptional adhesion to bare metal surfaces. It chemically bonds to the surface, creating a superior key for topcoats while preventing corrosion.

Ideal for galvanized steel, mild steel, aluminum, and other non-ferrous metals, this primer ensures that your paint won’t just sit on the surface—it will grip it and last.
