I've had work done several times (none of it our fault :grin at Artistic Auto Body on Huntzinger just off of 72nd. The work has always been top-notch and they seem to go over and above. While repairing some rear-end damage, they noticed that the entire paint job had oxidized pretty badly so they buffed out and waxed the whole car. Made it look brand new again. We were very surprised and pleased with their work. I know several others who've had work done there, and had the same results.
Not sure if they do custom re-paints or not. I got the impression that most of their work was insurance claims. But, it can't hurt to check them out.
