I am un-clear about the "quality" part of your question. Powder coat could have quality levels just like the paint on a Ferrari is probably higher quality than the paint on a Chevy. But auto paint is still auto paint. Powder coat is similar in process to glazing on ceramic kitchen dishes. The powder is applied and sticks to the metal surface by means of static cling. The item is then baked and the coating becomes glass like and molten and chemically sticks to the metal. The process creates a durable finish.Here's an excellent website on powder coating:http://www.metokote.com/coatingTechnologies/powderCoatingProcessSpecifics.asp
