I reinstalled my other bumper along with my new headlights with clear corners. Then just because I was bored I took my old nasty headlights out and restored them to like new condition. All I used was I wetsanded with 1000 grit for a while then upped to 1500 and then with the help of a friend got them polished. We used a drill press that we had put a cutting pad on and used Plastx for the polish.
