The top of the headlights on my G SRi-T have some type of sun damage/oxidation on them. It is definately on top of the plastic surface as I can feel it with my finger. First I tried Meguiar's PlastX which did nothing. I then tried Meguiar's Deep Crystal Paint Cleaner which cleaned up most of it on one of the lights, but that took quite a few applications and alot of elbow grease. Does anyone know of any chemicals or polishes that will take this off easier and wont harm the plastic? The light pictured is the worse of the 2.
