I did it a small shop in grand rapids. That is all they do all day long is tint cars. I highly recommend this type of shop. I did not do my windshield as with black interior and 5 tinted windows it is already dark enough in there. But I like the looks and it will not cost much at all to do.
If you don't want the po pos coming after you, maybe try light tint on windshield and front windows, and limo on the three back windows.
