Some guys keep reapplying a protecting coating to delay the cloudy/yellow oxidation from returning, but it doesn't seem to work very well. Once that factory applied coating is gone, you'll find yourself with lenses that oxidize relatively quickly.

Very True. if you want to completely "be rid" of your headlight oxidation, get another pair (OEM or whatever). If you don't mind buffing the plastic regularly, go for it then!

Realize the 3rd gen headlights are very "flat" so manufacturing glass covers is very easy. The 4th gen headlights are very curved so making a glass "replica" would be incredibly difficult to do. Plus plastic is much cheaper (i would imagine)
