Hi, I recently purchased a 2013 G37X. There's a rather long scratch/scrap along the windshield of the car. I've tried to use turtle wax rubbing compound and a buffer to get it out, but I didn't have much luck with it. I don't think my insurance would cover a windshield replacement to fix it without paying a pretty big deductible considering it's not a crack, but a scratch. It's one of the things that isn't really a safety issue but more of a major annoyance. Any idea's of what I could do to try to get it out? Thanks!

Cerium oxide, if the scratch isn't too deep.

Thats from not replacing wiperblades. My blades broke on a long-distance night drive and caused the same thing... Never could get it out.

Try a medium or aggressive clay first before compund and polish.
