Getting the rubber around it if everything is warm and you are careful seem to be OK as we did that 4 out of 5 times. It is the pulling the rope out and hitting the glass with the hand that seems to be the problem. If it does not go in easy and you hit it too hard with the flat of your hand, it cracks and it is time to purchase a new windshield. The glass people say if it breaks, sorry, will come back after you purchase a new one.
