I'd like to hear the results of measuring the temp of the inside of the
poptop with the same IR thermometer on a white poptop and a dark poptop
parked next to each other. That should be easy enough to arrange. Just
configure the windows on both the same and let them sit for a while to
stabilize. The temperature of the inside of the poptop should correlate to
how much it radiates to the interior, right?
