You've inspired me to get my windows UV tinted (think Suntek carbon) (I justify $ for health reasons as I'm sensitive to the sun! Homelink will have to wait!!)) Read somewhere that the roof glass has very good UV protection, the rear sides since not double paned are the worst. The front sides and windshield has some decent due to the laminated glass on front and double paned on sides. Sounds like ceramic has 99% UV protection, regardless of color and darkness of shade (at least that's how I'm reading it, so thats cool!
Anyhow, overall was feeling so lucky today to be able to drive this really lovely car!!
