About Rainbow Custom Powder Coating We are a custom powder coating service located in Columbus, Ohio. We pride ourselves on superior customer satisfaction. Our experienced experts will not cut corners just to get the part out the door fast. We stand behind all our work. Powder coating is a finishing method commonly used to apply an attractive and protective cover to bicycle and automobile parts, household appliances and many other types of metal items. This process doesn't rely on conventional paints or liquid binders. Instead, a dry powder is applied to items through an electrostatic process and then cured at a high temperature. As heat is applied, the coating evens out and “flows” over the item. The resulting finish is much more durable than traditional paints.
