Plastic headlight protection coating

Wrong! From the factory, the polycarbonate has a protective coating. The coating wears away in time and exposure. Polishing removes the last of that coating, so once polished, they remain clear, for just a few weeks. The only fix, is to re-coat the surface, with a UV protection film of some sort.

"Polysiloxanes" tend to be the original manufacturers' coatings. (Also used on spectacles with "coated" plastic lenses). They can't really be applied by hand, though. Best we can do, is use UV-resistant aftermarket polishes like the stuff JohnD linked to.

And I think (but am not certain), that most manufacturers use impact-modified acrylics rather than polycarbonates as the underlying plastics.
