My 20+ year old Chrony screens have finally bit the dust. The age and sun weakened plastic has broken so many times the clear packing tape I covered them with doesn't even hold them together anymore. I don't use them if it's cloudy, but they are needed when it's clear and sunny. I figure I'm not the only one this happened to, so what have you inventive guys used for replacements? I thought about it for the last week or so and have drawn a complete blank.
I looked in the local hobby/craft store and hardware store, nothing I saw would be suitable.
