i am a powder coater and we coat a lot of show car stuff , ranging from wheels to motors , heads , we do glass, wood, alum , steel , just about anything that can handle the temp. all of our race cars are powder coated and it is hard to chip if it is done right !!!!! we do alot of Harley tanks fenders an so on , it will hold up 5 to 10 yrs compared to paint !!!!!
