Abstract: Automobiles are transported on train cars called auto racks. These auto racks are covered by galvanized steel panels that are mounted by brackets to the auto rack frame. The brackets and frame are typically formed of a metal other than galvanized steel and the interface between the two metals cause the panels to rust and crack. Applicant has solved this problem by coating the brackets with a nylon coating that prevents the panels from rusting. Brackets that are to be welded to the frame are left uncoated at their weld points but are coated elsewhere. The invention results in an auto rack panel support system that will prevent rusting of the side panels and allow them to be used for longer periods of time.
