Hmm. Sounds like they have been etched by something harsh. Perhaps acid rain. I would try a few layers of Meguires NXT wax. Mine look great with it on them. Other than that I would try some sort of polish so long as it is not too abrasive. You could also try vinegar to make certain that it is not hard water deposit/build-up.
Good ideas. I too have this issue. It looks like a chemical burn almost. At first I worried that it might be the products that I am using, but I have since verified that it is not. I will try the vinegar followed by some nice wax. If that does not work, I am going to turn to more aggressive polishing. I think Eastwood offers a kit for polishing plastic/polycarbonate.
I had this same issue along with a couple of other folks in Norcal I have talked to. I was washing the car and was like "did I spill something on here?" as it sort of looked like it was from liquid or something. We think it may be caused by the glue that holds the protective film on the headlights during shipping.
Whatever it was, detail spray had no effect and ended up using Maguires Scratch X polish and it came right out and the headlight looks new again.
so I washed the Z this weekend and experienced this Fog on the outside.
What I found was it was the car wash detergent leaving some type of film on it. I got some dish detergent, wiped down the lens, rince, dried immidiately and whiz bang - nice n clean, no fog. I used the car was detergent again and was able to replicate it.
I SB has the right idea, I am gonna give it a try.
