Oh, man, I feel for you. I worry about any car I drive getting the same treatment IF I'm parked in a neighborhood with a lot of punks on foot. A couple of days ago 2 of my neighbors cars had windows smashed in. I wonder what goes on in kids minds that do this kind of stuff. The Eos is such a shining beacon that probably attracts this kind of activity.
I know what you mean about using you insurance, but I figure that's what its for IF the claim is over a certain amount ($500-$1000.) A couple of years ago I sucked it up and paid for an accident. My theory is IF the car was parked at the time of any damage, the insurance company shouldn't hold that against your record.
As for rubbing out the damage, I would be surprised if you could do it so that it wouldn't catch you eye every time you glance at it. That said, about a year ago I was backing up my former Mustang convertible and rubbed the rear bumper (other side of the car) against a concrete post. When I feel and hear the noise, I was really pissed at myself. I pulled ahead, got out to check out the damage and say what appeared to be really bad scrapes from top to bottom. I figured that I would need a new bumper and this was going to be one of those things I suck up and pay for myself.
I drove home, got out, and was looking for a way to hide the damage from my wife until I was able to get the car into the shop for a new bumper. I should mention the bumper was plastic (similar to my Eos.) I got some car polish and started rubbing over the damage and before my eyes, the damage (scratches) disappeared. I couldn't believe my eyes!
On another car, an Acura TL, we had about a 5" scratch on the rear fender (maybe caused by a shopping cart.) I rubbed that one until I was silly without making it disappear. So I took the car to my regular repair shop that give me a good price (if I have to pay.) He used some kind of professional wax rub that made most of the scratch disappear, but I could still see it if I looked closely in bright light.
Keep us advised as to how this turns out. Hopefully I won't get "keyed", but you never know. I probably shouldn't mention this, but IF it happened in front of your home, you may get the same punks waltzing by your place again.
