what happens to window tints on a car over time?

Question by Danny: what happens to window tints on a car over time? you see these websites that offer to tint your windows using a dark film they put over the windows but i was just wondering, wont this film get torn off, ripped or develop bubbles over time of driving at up to 70mph? also how are windows originally tinted on brand new cars - are they tinted using the same film or is the glass actually tinted?

In new cars the glass is actually tinted; it's easy to tell if you ever see a smashed window in a car; you would be able to tell if there had been a film on it. It's done that way because it's much cheaper than applying a film, and there's no risk of problems with the film peeling etc. On the other hand, aftermarket (meaning done after the car was made) tinting is done with a film applied to the inside of the glass, where there is a lot less wear and tear than if it was put on the outside. But even though the film's inside, after a few years it's not unusual to have problems like peeling, fading, bubbles, and discoloration. A lot of the quality of aftermarket tinting depends on having it done by a shop that has a lot of experience; you could use the best and fanciest film around, but if the person applying it doesn't know what they're doing, it won't look as good or last as long.
