I have a 1997 E420 with 150 k. The headlamps are dull. I have used cleaners, even rubbing compound using a buffing wheel attached to a drill - to no improvement. The service tech at Mercedes said that he has heard of some people using a very fine sand paper, 600 grit with water? to clean the lens.
Does anyone have any suggestions?
This is the second time I am posting this question....hoping to hear the miricle cure! Thanks guys!
