The MetalPro Etch Primer Grey and Black are formulated to provide excellent adhesion to non-ferrous metals, which can be difficult to coat due to their non-porous surfaces. The primer's etching properties create a rough surface that enhances adhesion, allowing for better bonding between the primer and the metal surface.

​

MetalPro Etch Primer comes in two color options: Grey and Black. The Grey primer serves as a neutral base, which can work well with various topcoat colors. On the other hand, the Black primer is better suited for use with darker topcoats.
