I had a similar experience. I had my Mustang painted there a couple of years back and when I went to pick it up, I inspected it first. They had painted over mud!!! They never washed the car prior to painting it. Needless to say, I pitched such a fit, they had to redo it.
So, a few weeks ago, my parents, against my strenuous objections, decided to get my dad's truck painted there. Upon 1st inspection, they found several areas where they had painted over what appeared to be dirt. It was pointed out to the clerk. He said they would tak it back and fix it, but it would take several hours to do it. So, when my parents went back to pick it up, I went with them. I fully inspected the truck from front to back. The places that my parents had pointed out where buff down, but looked horrible. There were drips of paint going down behind the tool box(that was removed prior to taking to them), and when I opened the passenger door, there was a huge area above the door frame that they didn't even paint.
They had used touch up paint on several areas as well.
My dad is pretty passive, but I'm not. When he went in to get someone to come out, I went with him. The guy started saying yeah, ok we'll fix this, but you won't get it back before next week because he has several people's cars that were scheduled to be painted the next day. I lost it. I told the guy that this was their screw up and this was the second time that it was messed up. My dad's truck WILL get fixed tomorrow before all these other cars because he was there first, and if they had painted it right in the first place, we wouldn't be having this discussion! I think I really scared that guy because we had the truck back the next day! It wasn't perfect, but my dad (the passive person) just wanted his truck back. Obviously I wasn't with him when he went to pick it up only because I had to work.
