This is a bit off subject; however, while flying in an aircraft with a

UV treated plexiglass is only slightly more expensive than the
non-treated. Being a 'homebuilt' group, I would think that most of us
would handle the UV problem while building.

Very good point, and I will make sure to use either anit-UV coated acrylic
or scratch resistant polycarbonate when I build.

I am no a doctor, and I do not play one on TV, but I have read that the skin
cancer risk from sunlight may be greatly exaggerated--at least for most of
us.

OTOH, having switched to polycarbonate eyeglasses, I can definitely saw that
the UV reduction is a *major* advantage. Reducing the UV level is a real
benefit to vision in bright daylight, with no discernable loss of night
vision, and might be usefull for heat reduction.

If anyone has a comparison between tinting and UV reduction with regard to
heating, the results would certainly be of interest.
