OK, dumb question, but how have you got your CK5 windshield sticker to stay on and not get ripped off by your wiper blades??? I thought I made a real good job of putting mine on. I went out in the snow and sleet and lost half the 'r'. Next time out I lost the 'l'. Is there a way of keeping them on or do you guys just never get rain or snow where you've stickers on your windshields??
