I have tinted every windshield I have owned for 15 years. I need to do this also
I did see/read a lot about it and alot of people say you can see the HUD better an possibly helps a little with polarized glasses when the tint is installed.
I will follow up when mine is done after my oil pump fix and let you know how it goes
I can't live without windshield tint or my costa del mar glasses...
