Hi, Dave,
The power of the sun over time is incredibly more powerful than a bullet.
UV degradation occurs to Lexan, degrading optical properties over time,
however I know of no studies concerning structural integrity due to UV
exposure, something that makes some acrylics brittle. Beware using dark
colors, or anything that could raise the temperature. Acrylics tend to
deteriorate with heat, and Lexan will be deformable at 100 degrees C -
heating is how they're shaped.
How hot will it be in the hottest day of the summer in the sunshine where
you live?
Why wouldn't you use fiberglass, steel or aluminum?
Best of luck whatever you do!
73,
Mickey N4MB
