Aloha,
If you've got a model with the tire pressure minitor, the only guaranteed way to keep it functioning correctly is to NOT use metallic tint film. My cousin had problems with it. As long as his windows were down, it functioned okay. Windows up, he kept getting low pressure warnings, no pressure indication or bad readings. Go ceramic, highly scratch resistant, 35% tint to stay legal (most places). The manufacturer (Formula One) says it has a 52% heat reduction and blocks 99% UV and has a lifetime warranty. The quoted price was $425. I knew the owner of the tint shop, so I paid way less.
