The issue is that a small station can be fined heavily if they inspect a car and it had tint. What you need to do is find a tint shop that will "sell you a receipt" which is dated a week or two away. Then you can show this receipt to the place that will perform the inspection and tell them that you will say the car had no tint when they inspected it. You could even have the inspection performed on the same date your tint was "installed".
Think outside the box, there are ways around most problems.
