Thanks for responding.

I've had stongard light protection film on my E46M3 for 5 years and 3M on my E36M3 for 3 years. The 3M hasn't colored...yet..other than it's normal light yellowish shade compared to clearshield. After 5 years the stongard has a yellowish tinge to it, but even that looks better than pitted headlights. And you can only tell it's yellowish after removing. While on, you could barely tell. I just bought some replacement film for about $60 and it's clear again....cracked headlights are ~$400 a piece for my M3 and probably more for the E70. I do a lot of highway driving, so it's a benefit for my situation....I'm just suprised I can't find any....sponors?
