We recommend that the sun screen is basically used on the inside of the windscreen, and the best way of fitting the sun screen is as follows:
1) Clean the windscreen(for best results with SonAX Clean Glass)
2) Moisten the suction pads if necessary
3) Fasten the sun screen on one side by pressing firmly on the suction pad, then apart and fasten the other side.
4) It is necessory to completely remove the sun screen. By loosening one of the suction pads, the sun screen can be rolled up and left up and left hanging on the side of the windsreen.
