Definitely stay away from the "chain" paint shops!
I had bought an 86 Conquest to putter around town with back when I did a six-month IS contract away from home. The original paint had already been too far gone to save, so anything would look better than that.
The "chain" shop did prep the body (removed dings and hail damage) before painting. For $700, it wasn't a "great" paint job, but it looked better than what I had originally. And again, this was a cheap car in the first place!
Two things. They use maybe two coats of paint, and don't rub down the paint after spraying, so you will see major "orange peel" throughout. And no clear coat is used. With that in mind, light colors look better (I had mine painted Dodge red), and if you do black, midnight blue, or whatever, the results will be a real disappointment!
