I can get my wife's G35 headlights clear as new with no problem, but they yellow again within a month or two. I tried Meguiars UV protector, and it does nothing... (did a side by side test). Duplicolor has a spray coating that's supposed to be pretty good. I did a test run on my Frontier's headlights and I like the product, but it's too soon to declare it a success.

Yep....any polishing of the plastic is temporary at best,as the act of polishing removes whatever UV coating that was there from the factory.Temporary solution at best,with the clouding/yellowing returning much quicker than it initially did.Shocking the NHTSA does not have better standards for this universal,growing safety issue with plastic headlamps.
