More people add window tinting to their cars than any other single modification. There's a simple reason that auto window tinting is so common. It makes your car cooler in the summer, and adds a certain degree of sophistication to the vehicle. There's a direct underlying benefit for getting the windows of your car or truck tinted. When you keep the ultraviolet rays out of your car, the damage to seats, upholstery, dashboard, or other items in your car is significantly reduced.

Other claims seem a little obscure to me. Here are a couple. 1) Auto window tinting helps improve your gas mileage. (huh?) The idea is the tint keeps your car cooler, which causes your air conditioning to run less, which causes less use of gasoline, which increases your gas mileage. Next you'll hear that global warming is positively effected by auto window tinting. 2) Your risk of premature aging drops with tinting. I'm guessing this relates to UV rays on your skin, but it seems like a stretch. And finally, my favorite one. 3) Your risk of cancer drops with auto window tinting. Another UV argument. It sure seems this business has great copywriters.

Costs vary from place to place on window tinting. You can pay as little as $45 to do it your self, or as much as $400 in a professional shop. The choice is yours.

There are a few caveats with this type of program. The Federal Government thinks all aftermarket window tinting is against the rules. States, who enforce the law, have a different view. Be aware, states have differing rules and regulations from one to another to the degree of auto window tinting you can legally use. Tints vary from 70 VLT (vehicle light transmission) for windshields to 5% VLT for limos. The amount of light allowed into a car varies by the window and state. Any reputable shop who does the work is well aware of the laws, and can help you stay out of trouble. Get the help of a professional to put all the guidelines into perspective before you make a decision that sees you get a traffic ticket for having tint that is either in the wrong place or too dark.
