I agree with Jeffahart. Chips, scratches and debris in the paint are definitely the painters responsibility and he should fix those with no cost to you. Panel fitment, panel gaps, wavy panels and such all depends on what you negotiated for. $6k sounds like you were paying for some bodywork and not just spraying paint. Unfortunately unless you have a list in writing on the bill/estimate of areas that were being worked on it's going to be hard to prove. Unless the shop is willing to work with you and fix the issues. But like Jeffahart also said, lots of places will try to make you just take their sub standard work and hope you don't come back making a fuss. Make a bit of a fuss.

That being said, it does sound like they rushed it out the door a little. Unless the hood is out of shape or the fenders are misaligned getting the hood fairly straight isn't that hard. Same with the cowl panel which wouldn't be chipped unless they were careless and/or forced it. If the shop took the hood, fenders, cowl panel off or were installing them then this is definitely their problem. Because it would've been their responsibility to get all the sheetmetal aligned properly and not chip it in the process. Sounds like they didn't do a thorough fitting before paint and just slapped it together.
