Not really because, its only suposed to be on your car for30 DAYS!!
They will withstand 30 days of weather, especially the new ones.
I have always been told to put it on the rear of the car but WNAPLAY is right.. i stand corrected.
but just for this kids reference
4503.21. Display of license plates and validation stickers or temporary placard or windshield sticker.
No person to whom a temporary license placard or windshield sticker has been issued for the use of a motor vehicle under section 4503.182 of the Revised Code, and no operator of that motor vehicle, shall fail to display the temporary license placard in plain view from the rear of the vehicle either in the rear window or on an external rear surface of the motor vehicle, or fail to display the windshield sticker in plain view on the rear window of the motor vehicle. No temporary license placard or windshield sticker shall be covered by any material that obstructs its visibility.
I am going to assume that last part includes tint.
