I'm putting a new shield on, and there is some tape that is on the visor piece right behind the windshield. It is some kind of slick plastic tape that sticks on to the visor I'm certain to allow the shield to slide up and down easily. What's left of it is in poor shape and a bit wrinkled and rolled up. Any ideas as to what kind of tape (product) this is, or any suggestions on what I could do here ??
