Don't limit yourself to DuPont or PPG. BASF, ICI, Spies Hecker, Sherwin Williams Automotive, Sikkens, are all top quality.
If you wait too long, you will be faced with the possibility of having to find a shop that does waterborne paints.
The undisputed leader is BASF Glasurit 90 Line. They have been developing this line for over 20 years.
If you are in California waterborne is all that CARB allows. It's much higher strength tints mean less color needs to be applied for total coverage.
But like previously stated it's all in the application and the pre-paint prep.
edit: I see you are in Pa. Joe from PA just had a front bumper replaced. He had high praise for a shop in West Chester,Pa.
Here's a link...
