If you're patient the
Langka kit with touch up paint can fix your scratch. I have used the Langak paint chip and scratch kit to repair rock chips with excellent success and I did a small scratch on bumper of my wife's Mustang. It's not perfect like it had been sprayed, you see what looks like distortion if done right, but from a couple of feet back you can't tell. So far it the best thing I have found but I am always willing to try new products if anyone knows of something they think is better.
