Tint all the way around in Oregon, no hassles so far. For a 13-yr old tint job, no scratches (clean with vinegar-based window cleaner, no newspapers or ammonia) but a small peal in the front driver's window on the front edge where you roll up and down the window, but cut it diagonally with a razor blade and looks intentional. With a black pearl car ya' gotta tink or cook. Good thing AC blows cold.
