Thanks Dave, the only time the canopy sees sun is in line, on the run
and returning to the pits. I will try to cover it when not on course.
Am adding a cockpit ac unit this year so that may help as well. The
light aircraft folks say that Plexus is the easiest and best cleaner
with good UV protection. It may be as good as it gets already...........
Lexan XL has apparently the best UV protection. I got mine (Lexan)
from Home Depot and don't think that it is "XL".
