There are several ways to repair the wheel hub: grinding, polishing, painting, baking paint and so on. Among them, grinding and polishing are the most common methods. Polishing is mainly to remove scratches and pits on the wheel hub surface by machine or hand, and then polish it to restore its original luster. Spray painting and baking paint is to spray a new layer of paint on the wheel hub surface to make it look brand-new.
It should be noted that professional maintenance organizations or technicians must be selected when maintaining the wheel hub to avoid secondary damage to the wheel hub during maintenance. At the same time, quality inspection is needed after repair to ensure the safety performance of the hub is restored.
