I want to tint the panoramic moonroof so I can keep the shade open and not have the sun beating on me when it's high in the sky. My tint shop tinted my front windows and a strip along the visor, but would not tint the moonroof. They said tint could actually cause the glass to crack over time. I researched this online. A bunch of sites say you can do it, and a bunch say you can't. I was hoping for an overwhelming majority of web sites leaning to one side or the other to help me make up my mind, but I still am not sure. Any insights??
