I must strongly disagree with Eric's post!!!

He talks about wrinkling and skin damage (sunburn?). Well, if you are only
concerned about sunburn and wrinkling, then go ahead and depend on the
canopy for your protection.

However, nowhere in Eric's post does he mention SKIN CANCER!

The UVA range of the sun's spectrum has a longer wavelength and penetrates
right through your canopy and deeply into your skin. There is a large body
of research which ties UVA exposure to skin cancer.

Your obsession with UV exposure thru canopies makes me laugh. You are
likely getting far more exposure standing out on the ramp waiting for a
tow. How many of you realize how poorly many fabrics protect you
against UV? Not many, based on this collective list of responses. I
remember a story an old physics instructor told me about a checker
board pattern sun burn from wearing plaid shirt while hiking thru the
Italian alps during WWII. Your light colored cotton shirt has only a
SPF of about 10 (or less):

The good news is that there is a laundry product called Sun Guard that
can improve this to around 30:

Also, Plexiglas blocks over half of the UVA spectrum, and this is the
shorter wavelength, higher energy half.
