Taking mine on a 180 mile round trip tomorrow to check the mileage. I have decided to get the back and side glass tinted with Lumar.
50% on the back and 30% on the sides. Did my Comet last year and what a difference it made!
The tinter wants me to take the back "coupe" glass out but I don't think I will. Too much chance of damage to the 68/69 stainless trim
and breakage of the window. He can tint it in place, he just doesn't want to. Will post a photo when complete.
