I have done a bit of research and I keep seeing a ton of people saying "Don't tint the outside of windows because its exposed to the elements DUH!"... but I have not seen a single video or evidence of someone having tried this. Seems to me like people are just repeating a consensus that has not been properly tested, and since its a *&$#! to remove third brake light for an 01 grand prix GT, which is required to properly tint interior of rear window -- why not tint the exterior of the window? What's the Big deal with tinting the exterior of the rear window??? What environmental factor is external tint exposed to that internal tint is not?
