More seriously: You don't say how far up the food chain you've gone with Chrysler. Whoever is saying 'no' has a boss. Talk to that person. If it's the service writer, talk to the owner of the dealership. If it's the owner of the dealership, talk to the Chrysler "zone rep". If it's the zone rep, find out who (s)he reports to. And so on and so on. You could even try writing in to "Ask Dr. Z" to see what "he" says about the situation. They ask for enough personal information that someone in Customer Service may respond.

Does the dealership you went too actually have a body shop? If they do, I don't know why they wouldn't just repair it if the paint is still under warranty. It would be no skin off the shops nose. Service writer fills out paperwork indicating paint delamination on the bumper. Their body shop fixes it. They get paid for the repair from the manufacturer, though at a lower rate than if you as a customer had to pay for the repair.

If it's out of warranty, that's another story. Even though the paint shouldn't become delaminated due to a scratch, you're at their mercy. Good luck.
