Definitely keep on the dealer's case and don't accept anything less than a proper refinish. If you need to call DC, go for it. Maybe your sis might know someone who could apply some pressure.
I had a similar service problem with my wife's new 300m Special. I had brought it back (again) for a transmission malfunction and the dealer scratch the front bumper cover (about 8 inches). This car was less than a month old and had less than 1K on the clock. To make a long story short, they tried to bandaid the damage on the cheap and it ended up looking up worse than the original scratch. It was quite insulting to hear the bull that they expected me to swallow about body and paint repairs. The last time, one of the guys at the service desk "buffed out" the bumper and pronounced that it was better than the one's on the lot and that was all that they would do. The finish had the texture of 400 grit and there was a definite color mismatch where they had "worked" on it.
I ended up paying a reputable body shop $700 to have the bumper cover removed and refinished (stripped, primed, new color and clear coats). It is a perfect match and the finish is actually better than when I bought it. The body shop warrantied the job for as long as I own the car. The dealer could have had the work done for a less at the same shop with their business discounts but did not want to put any more money into customer service than absolutely necessary. They didn't even try to fix the transmission but kept trying to give the car back to me saying drive it and the problem would go away on it's own. This was a $40K car for Pete's sake, not a Yugo.
I finally took the car to a dealer about 25 miles away and they replaced the front transmission pump (a documented problem) and I've since been driving the almost 50 mile round trip for 3 years for service. Before going to them, I checked with the Better Business Bureau and they had a clean record (no complaints filed). I bought my new Charger from these guys because of the good service I had been receiving with my wife's car. My original dealer had a rap sheet with the BBB (ya think?).
I hope you can get your baby properly fixed without the pain and frustration that we had to go through.
BTW, my wife also has same seperation anxiety when I drop off her car for service, even though it's usually only for the day. I think you two would hit it off.
