Over a couple of days I have been working intermittently on the wing root fairings. Used a dremel sanding cylinder to smooth out the worst of the ridges in the fiberglass molds made last time the wings were on. Brushed on a couple of coats of white Flex-Seal liquid rubber and let dry between the coats. Used the Dremel sanding again to further smooth it out. It will probably take another 2-3 coats to get the thickness I'm after.
