The most important step in powder coating rims, regardless of the size, shape, design, or application of the rims, is to clean the rims thoroughly and remove any grit, grime, grease, or dirt. Any foreign substances on the rim may prevent the powder coating from adhering correctly or setting up properly. Many professionals will sandblast all sides before powder coating rims to ensure any grit and grime, as well as old powder coating or painting, is removed prior to the powder coating process. Once the sandblasting has been finished, it is a good idea to clean the rims once more and even apply a thin layer of wax to ensure proper adhesion.
Ensuring all proper tools are present before powder coating rims is essential. Starting the process without the proper tools can result in a poorly finished product or incorrectly applied powder coating. If the owner of the rims is intending to take them to a powder coating company, he or she should be sure the company is well-stocked for powder coating rims and curing the powder coating properly. Choosing a reputable company with competitive rates is essential; if the owner plans to do the powder coating himself, he or she should be sure to acquire all the proper tools for application as well as curing. If it is the owner's first time powder coating rims, it is a wise decision to practice on scrap metal before attempting the process on the rims.
One of the most important steps in the process of powder coating rims is the curing process, in which the powder coating material is essentially melted so it runs and covers the entire rim. Before the curing process takes place, one must ensure the powder coating was applied properly, and any parts of the rims that should not be powder coated are adequately protected. One should remember that powder coating may work into the lug holes, which may narrow the holes slightly. If this occurs, it may be necessary to ream out the holes to allow the lugs to fit properly.
Rims can be powder coated in a variety of colors. One should be sure to decide the right color for his or her vehicle before the powder coating process begins. Most powder coating companies have sample cards that feature the different colors they offer. Be sure to check these cards carefully and consider which color will work best for the vehicle. Choosing the wrong color or finish may mean having to start the process over, which can become cost prohibitive.
