Abstract: A process for finally finishing a surface of a bronze sculpture that is then waxed with at least a single wax coating. In a practice of the invention, to a bronze surface that has been polished and preliminarily buffed, a low pressure grit material flow is directed against a section of the bronze surface as a final surface texturing step and, where a surface or surfaces adjacent to the section is to be painted, patinaed, or is to receive a like surface finish, a selected plastic material is used to coat the section of the bronze surface, which material is applied as a liquid and dries to a flexible surface that adheres to so as to essentially render the bronze surface imperious to contamination with paint, water, or the like. After application of paint, patina, or the like, the plastic material coating is stripped away by a painter/operator using a tool or tools, such as a pair of tweezers, to remove the coating. Whereafter the sculpture surface is waxed.
