Deb, is this clear coat on the fog lights an actual spray on clear coat (ie, clear paint) or is it more like the 3M clear film? If it's clear coat paint you may be stuck with it, except that if it lacks clarity you can probably buff it out a bit with something like Meguiar's Ultimate Compound. Only issue there is you've got a small area in a fairly tight spot to work with, and you can't easily get a buffer in there so you're looking at some hand work. If it's a 3M clear film, why not just leave it in place? It will help protect the lens from fading, no doubt about it.
