Yeah, detailing is just a cleaning. It may clean up minor scratches, but not dents, and certainly not the gas filler door. A full interior and exterior detailing will run around $200 (I paid $180 for Ziebart to do it to my '98 Sebring convertible, but they did not clean the top like they said they would). For what you are talking about, you need to go to a scratch-and-dent minor body shop. I have no idea what kind of jing you are talking about there.
