Well, for a few years my headlights in my 2000 GT were getting progressively worse. Eventually, they got so bad I might as well have driven around with my fog lights on as headlights. I really didn't want to spend the hundreds to replace them, and no product worked to clean them off....until recently.
I found out about this headlight cleaner through a friend. It's made by Crystal View Chemicals. It has a lifetime guarantee so i fugured why not give it shot (although I was still skeptical). I ordered it online and tried it out this weekend and to my surprise, it was nothing short of perfect. My lights went from yellow and foggy to looking brand new. I took a bunch of pics and when i get my computer home I will post them. They don't look any different from the pics on the below web site.
So if any of you have been or are battling the same issue, try this stuff. It works. Here's the site:

It sounds like a cheesy site, but they were great. Stuff came in two days. Phenominal!
Post up if are thinking of it or with any questions.
