Yeah, I guess you're right.
When the white car gets dirty, it just looks like a pearl color...but I can tell the difference. When I first got the car, I had what looked like little brown spots in the white paint all over the hood...you could only see them when you got your eyes really close to it. I think it may have been parked under a tree or something, dunno. But we tried the clay bar on that, and it just didn't help. It's been over a year now, and i don't notice the little spots that much anymore...
Is it oxidation inside the plastic in headlights that makes them look so hazy? I hate that the most...I already replaced one of the headlights because that was bothering me. The car looked alot newer just with the new headlight. The other one is starting to turn...don't know why the one on right was like 10x worse.
