I cleaned my foggy headlights yesterday. They were in really bad shape as you can tell from the before picture. I got this headlight cleaning kit from Advance Auto Parts anda bottle ofMequiars PlasticX polish. The kit comes with a drill addapter and some foam pads to stick on it. I had high hopes for that kit but was disappointed with the results. I think it's useless if your headlights are really cloudy like mine were. After using that kit for a while I gave up and decided to try some hand sanding. I used 400 grit then 800 grit and then 800 grit wet. Then i went back over it with the kit. I put some of the Meguires polish on the foam pad and that seemed to work well. They're not perfect but much better then before.
