I have been lucky in not having to had any screens replaced for some years now. My only criticism refers to a screen that I had fitted to Gleaming Beauty some twelve years ago. My understanding was that it was China sourced, and it was impossible to see through the screen when raining, day or night, even after several attempts at cleaning the unit. It was just an oily film that seemed to be impregnated in to the screen, and it was about impossible to drive the car at night when confronted by oncoming lights of ANY description, not just cars.
In the end, the installer replaced that screen with another unit. My only recent experiences. Regards Styria
