This post is educational at least. Sorry to hear about your paint job. Got screwed by ABRA Auto Body & Glass when they tried to paint a Cadillac Eldorado after a side impact collision. It was a battle trying to get them to correct it and it never did get fixed. Had I been older and wiser, I would have known what to do and say from the git. Learned to never go to Safelite auto for a windshield either. Two different vehicles and two different tech's botched my glass installs.
If we could hijack your thread and create a sticky with listing places NOT to bring your vehicle.. You best bet if you don't already have a solid network circle for things like this is social networking. Now days you can find a badass painter, references, and examples before you ever set foot into their shop/garage/barn. Try and communicate via e-mail your expectations and have your legally binding document right there without any effort. Most of the guys I'd use for paint are friends of friends and I've seen the work first hand. Some of these are small no-name shops, chops, or people doing work outta their pole barn with high-end equipment and years of experience. Some of the best deals are had outside of chain shops too. About a year ago my buddy had is STS-V painted Onyx black and all the dents removed for less than $200 and some side job bargaining. Good luck with the fix - as others said get into small claims and get your money and maybe something for your waste of time back. Your time is worth more than $1600
