I just put in new headlight housing in my car, and the other lights just didnt look as crisp compared to them. So I had a few extra sanding discs from a headlight lens restore kit so I figured to clean up the upper corner turn signals, then cleaned up and look better, I looked at the lower bumper turn signals (AA Body) and they have almost a raised checkerboard design on them so the restore kit would take foreverto get the ridges down. I grabbed a belt sander and got the ridges down and followed up with a hand sanding, then did the sanding discs and polish from the restore kit. They are noticibly different, not sure i like how they loook, but they look cleaner and not cloudy like before...
