hi guys, I just bought a z3 a few days ago and it had awful headlights. However, after buying the car i didnt want to spend any money so i decided to try to clean up my headlights. Pretty much the only thing I did to them was wet sand them and then buff them and they have gone from looking bad to looking insanely close to new. I made this video about how I did because it worked great and I wanted to share the idea with others.

Here is the video i made:
