As long as it didn't go through the clear you can get any good scratch remover to take care of that.
That sucks tho, I hope someone got the plate and reported them although without a dash cam it would be hard to get anywhere. More and more ppl are installing dash cams these days tho.
Anyway, like I said as long as its just a surface scratch in the clear you are good. I'd give Meguiar's ScratchX 2.0 a shot, I've had good luck with it in the past.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
