I've got 35% tint on the TL (ceramic). I have no idea of it's properties compared to the metallic tint, except that the metallic version interferes with SATNAV receivers.
I've got Formula One tint on the TL, and my wifes Odyssey, and previously had it on my Civic SiR. Never had an issue with fade, peeling or scratching. Good stuff and worth the money.
