Yes, nC Corrosion Passivator Primer 2-in-1 is a direct-to-rust solution and should be painted over for the best results (after 4 to 6 hours at 20°C). Corrosion Passivator 2-in-1 stabilizes the surface by converting rust into pores and binding it to the metal. This provides long-lasting protection and better adhesion of the next layer of coating due to extra roughness of the surface.
