The bigger issue is with flying in rain. The highly polished, waxed
finish will bead up with water droplets. The rougher surface will
shed water without forming the really draggy (is that a word?)
droplets. Same as if you waxed your windshield in your car, water
beads up instead of sheeting off. So if and when you have to blast
through that virga line the drop in performance will not be as
severe.

So, should we be using RainEx on our wings?
