QuikSnap is not only an alternative for illegal paper tints. It is also removable and can be used as per demand. We recommend installing quiksnap while the car is parked. However, The Passenger doors in a sedan can apply quiksnap even while the car is on road because all it does is protect you from Scorching heat, providing you with ideal brightness and temperature inside your cabin coming from the UV sun rays that can be harmful for us and our children.
You want it or you need it is a confusion that remains. One must have it.
