My 2005 headlight covers are really bad on the bottom of the lens as well. I buffed with 3M product which appears to have done an OK job but it looks like they are equally bad on the INSIDE. I can't find any info or discussion on this. Anyone? Tried to remove the entire headlight and couldn't, finally found instructions, but before I try I wanted to find out if I can remove the cover to clean the inside or is it all one sealed unit? Seems like a great deal of work to remove.
