A few months ago I posted my problem with clouded headlights that were once clear. I know that the responses I received were mainly telling me to replace the headlights. I did have some success in fixing the problem. First of all, I spent lots of $$$ on "headlight restoration kits" that did not work. What did work, although they are not perfect but at least Clear is; I sanded the headlights with "ultra fine" 600 grit wet/dry sandpaper. I kept the paper wet with water while sanding. I sanded each headlight about 15 to30 minutes. After that I used a buffing wheel and buffing compound (made for plastic) in my battery operated drill. I had to buff each headlight about 30 minutes. I also used "Bluemagic" Plastic & Plexiglass Cleaner. and after I was somewhat satisfied with the results I applied "Bluemagic" Liquid Metal Polish to seal and protect. I did this at the beginning of October and the headlights are still clear. I had trouble finding a buffing wheel and buffing compound. I ended up going to a hardware store but I now see that Sears carries the buffing wheel and compound. This is at least an alternative for those who don't want to spend the money on new headlights. Hopefully it will help someone else out.
