There are a few different reasons that car owners may believe they need to add tint to their windshields – some of which are more valid than others. Some think that this will keep the air inside the vehicle cooler during the warmer months, while others just believe they simply look more stylish rolling down the highway with a tinted windshield – sort of like sunglasses for their prized ride. What really matters, though, is whether this option is legal in the state where you live (or that you are moving to), or whether you are going to have to get the whole windshield replaced.
