Abstract
A method of finishing a metallic surface includes the steps of: disposing a mask layer onto an initial metallic surface of a substrate, etching at least a portion of the initial metallic surface with an etchant to provide an etched surface, and separating the etchant from the etched surface. The etched surface is smoother than the initial metallic surface. On a depth basis: the etchant etches said at least a portion of the mask layer and said at least a portion of the initial metallic surface at substantially the same rate; and/or the etchant penetrates said at least a portion of the mask layer and etches said at least a portion of the initial metallic surface at substantially the same rate. A substrate finished by the disclosed method and a kit for practicing the method are also disclosed.
