Plexiglas = acrylic, so yeah, that's not stopping UV, but UV can make it yellow and weak. IIRC it also shatters into sharp shards. Not what I'd choose for a canopy. Lexan = polycarbonate = more better. PC eyeglass lenses are considered UV blocking. They're strong, moderately high index, and block

Plexiglas does pass enough UV to cause sunburns, as I've gotten them in the past in an airplane. When we repaleced the windshield in the C182, I bought one with 95% UV blocking and could only get up to 50% IR blocking. It is noticeably more comfortable than plain Plexiglas, whether tinted green or

Even if the UV doesn't kill the virus, a mask on hot dashboard in the sun would not be hospitable for the virus due to the temperature. Might not be an instant kill but doesn't seem like an environment where it would live very long, as it doesn't seem to do well on paper or porous surfaces to

And most automotive glass is glass with plastic. Today just about all automotive glass has at least a little tint on it which would, I'd think, remove any UV. I read the other day that a mask does little to protect you from random COVID. Supposedly the mask keeps you from passing COVID to
