The reflector on my LM 21w HID is looking very dull, scaled, deposits, distortions... I don't know how to describe it other then it looks like crap. And I've been noticing my light output looks about the same.

Has anyone ever seen this? Can it be buffed out or something? I see LM has a replacement part on their site but it's' $150. I' m wondering if there's any way to salvage what I have kinda like restoring headlight covers on an old car.
