I don't believe that painting would knock it out of balance. You would have to go out of your way to put 25 coats of paint on one side to cause any problems. I would think that the rust would be a bigger issue. Just my $.02dennisbaker said:I thought about the painting or powdercoating but was afraid of the balance issue. The rust on the underside of our cars really bothers me especially the axle. Sounds crazy I know. Just doesn't make sense that part of the underside of our cars is nicely finished and part is a rust bucket.
