My next addition is going to be tinted windows. I live in Michigan so the rules here are going to be different than, say, Florida. Do I go to a local shop, or should I go to a big box place like Quality Truck and Auto? How much would be a reasonable price to pay? I was told that they don't use precut pieces, they have to do custom cutting, so that adds to the cost. I don't know anything about the % transmission of the film, but I have to assume the shop will know the details on that. I want the tint to be dark, but I don't want a cop magnet. Any advice fellas and fellettes?
