Too much heat is hitting the top of my balding head. My car is going into the tint shop Monday and the proprietor says adding tint on the roof glass will not help at all. Does anybody have experience with this, who can comment on whether it helps or not? It is not an issue of cracking. I also know about the roof shade insert, which I will order if people say tint won’t help. Also please hold the bald jokes, including Rogaine suggestions. Thanks!
