The most important advantage of window tint is ironically the most unknown. In vehicle accidents which would usually cause the windows to shatter, spraying the occupants with hundreds of tiny sharp pieces of broken glass, the strong adhesive tint film will hold the cracked glass together preventing it from doing any damage. Any quality tinting film will be strong enough to hold the glass together even in the worst of accidents. I've heard tons of horror stories about injured crash victims who've been sprayed by the tiny shrapnel-like bits of glass, mostly from policemen and ambulance drivers who've been scared straight from accident scenes to my shop.
