nope....even on a mini maglite i've carried for 5-6 years, the scratches (which are very bad) haven't affected my use of it. before i got my arc LSH, i had a C2 which i bought with a lexan bezel specifically because i intended to use it hard and durability was more of an issue to me rather than looking pretty. one of peter's tests to show the durability of the arc LS was to throw it hard enough on the floor to make it bounce up, and i'm sure a pyrex lens wouldn't survive the impact.
alexgt, i've used toothpaste on tissue paper to polish lexan lenses with good results /ubbthreads/images/graemlins/smile.gif
