Tips on removing key marks.

Seems like you cant have a nice looking car these days. Well for the first time my blazer got keyed in the back. It didn't go all the way threw to the primier but it scratched the paint. It just looks ugly. I tried to buff it out with some compound and that seemed to help but it is still visible. I just want to see if anyone else may have something else i could try. Maybe Colorsanding?

repaint it bud

There is no way you are going to get it out.
