UV Coating beginning to delaminate from front grille and headlamps. Solution?

[Green1995SVX]

So as some of you may know, our SVXs came with a UV coating on the headlights and grille which prevent them from yellowing. Once this coating wears off whether from peeling, or from being "sand blasted" away by highway driving, the headlamps begin to yellow. Today I noticed that mine is starting to delaminate at the very top center of the grille. I can't stand the thought of having yellow headlights and am wondering if anybody has any input on how to stop this process from getting worse. Perhaps the only option is to buy new headlamp and grille units?
