As soon as I get my new glass, I plan on putting a couple layer of helicopter tape on the bottom 2" and wrapping it over the exposed edge. I notice all the cracks start at the bottom, and both of mine were hits, one serious, and one almost non existent. I haven't seen anyone have a crack start in the middle or upper yet, so I'm going to focus on the bottom, and leave 95% of the screen clear of plastic cover that will degrade. I don't know the reason why, but It doesn't appear to me the entire windshield is failing, just the bottom. If I have finite resources for engineering and design, I focus on the known points of failure.
