Abstract: The present invention relates to the application of surface coatings to treated aluminum articles utilized on aircraft, and more particularly to a system for masking portions of aluminum aircraft wheel and brake components for application of surface coatings to reduce or prevent wear and/or corrosion to the aluminum article. The system may be utilized for new aluminum aircraft components as well as aircraft components that have been subjected to non-destructive testing. The masking components are constructed and arranged to cooperate with portions of the aluminum component in a sequential manner to allow for application of multiple layers of primer and/or topcoat without removal of prior masking components so that a coated component complies with the manufacturer's written requirements for that component.
