Do you have any cutting pads available to you? compounds? You can probably put a pretty good dent in it if you have a cutting pad and some compounds like M105 or Megs UC. It's going to be some what time consuming. Honestly, I'd just wait for your PC to come in. You PC will make quick work of it.
I've noticed on LR's if the clear isn't protected well a fingernail scratch looks like it was keyed.
I use my Disco in places above no roads (release from detail ocd). The screeches and howls of honeysuckle going down the side would make most cringe.
The marks look quite bad but clean up.
Wait for your PC. It will be your new friend. Let us know how it turns out.
