Claim:
1. A method for producing a covalently bound, monolayer protective coating on the surface of a material, the method comprising: (i) activating the surface of the material by contacting the surface with a surface activator that increases the concentration of polar binding sites on the surface to form a polar surface, wherein the surface activator comprises an organic solvent and a first fluoride-containing compound selected from the group consisting of barium fluoride (BaF (ii) coating the activated polar surface of (i) with a protective reagent that reacts with the activated surface of (i) to form a covalently bound protective coating; and (iii) thinning the covalently bound protective coating by contacting the covalently bound protective coating with a thinning agent that removes additional outer layers of coating and contaminants, wherein the thinning agent comprises a surfactant and a second fluoride-containing compound selected from the group consisting of barium fluoride (BaF to form a covalently bound monolayer protective coating on the surface.
