repair

Due to my OCD, I ended up scratching the windscreen on my slingshot while cleaning it. It doesn't seem too deep but its enough to bother me. Has anyone had any luck buffing out a scratch on a tinted windscreen or is it even possible?

Someone wasn't watching when they were weed eating. It's one tiny spot about the size of the eraser head on a #2 pencil with a a little spidering from the center. How would be the best way to repair it.
