I don't know. For a guy who does custom air brush work I would imagine his hourly rate is probably $60.00 or higher per hour. Figure 40 hours to do a cut and buff on the complete car...... When you get into the high dollar custom paint and graphics it's probably not ridiculously out of line.... High by what a lot of shops charge, but based on your information on the work being done it's right in there with the rate for that kind of high end work.....
