Gonna tint front windows on my GX460. Xpel dealer 30 minutes away. Llumar dealer 1 hour away. These 2 will be my choices to choose from. My heart is leaning towards Llumar. Tried and true. Any suggestions? How many of you did your windshield? My understanding is the factory tinted rear windows have no IR (heat) protection. Did you address that issue or not bother. I know to go ceramic. I’ve never had a car this nice and I want to minimize my potential mistakes. I have seen some films are bluish. I want the film match the factory color. Not the darkness.
