You can enhance the look of your car by refinishing the wheels with the appropriate paint. Before you dive into the application process, you must consider an important point. Car wheels are made of metal, a surface that will not accept paint adhesion unless it is etched. Unfortunately, car wheels are too durable for the same friction-based etching techniques used to prepare plastic and vinyl for paint. You must use a special primer, engineered with acidic qualities that give it the ability to etch metal.
