Dennis and Chaz, it IS powder coating but it's a zinc based primer they shoot in-house. It's not only chemically incompatible with most powder manufacturers' products, it's on there so thick you'll almost have to paint them -- be ready Chaz, because only excessive blasting will remove it (and getting a good ground even then is impossible if you decided to go with powder). I'll never work on another rim from Wheel Vintiques.
