I just got off the phone with a reputable guy in Manhattan (who does celebs' cars) and he quoted me $475 to do all windows w/ Huper Optik. I think it's a pretty good deal but I'm still concerned about how weird it would look if by law the front windshield and 2 front doors require 70% while putting darker on the rears. I'm allowed to do anything else on the 2 rears and rear windows so seeing that 35% is a sweet-spot, I want to do that.

He said he could put a 45% on the fronts that don't appear to be any darker than the requirement to the naked eye, maybe I'll go closer to 60% like above, but that's much different than the 35% rears. What do you think of this? Anyone with pics?

I want it to look as uniform as possible throughout the vehicle.

BTW, I'm still curious what % it is from factory as it looks somewhat tinted already.
