The headlamps on my GT have not yellowed, but are now getting foggy. It is most noticeable when the lights are on. Rather than a uniform haze, it looks like the polycarbonate might be pitted.

Has anyone had success clearing up headlamps. I would appreciate info from anyone who has had lasting success. What did you coat the headlamps with. At this stage I am thinking that sanding will be required. I don't imagine carnauba wax will be a long-lasting protector. I imagine spraying on clear coat that contains UV inhibitor will be the go.

Comments most welcome.
