Through experience on long rides, my windshield comes off with a couple of screws and goes into the bathtub at the motel to soak to remove bugs.
Poly is a little better but not much.
I do use a silicone based stuff given to me to clean my windshields. Looks like old school Armor All. Supposed to make stuff not stick to it.
Is there a hidden reason you are cracking windshields?

You do know Lexan is polycarbonate right? Lexan is just a brand name for polycarbonate.
There are different grades of polycarbonate. Scratch resistant Lexan M10 is what you should be using.
