The entire bottom side of the ez got sanded with the DA sander in prep for filler and finish. A few places have deep voids that I'd rather fill with Micro than Z-Grip so after the sanding was finished I filled these areas. With the left over Micro I also built up the start of an airfoiled trailing edge right behind the roller bearing in the nose. I'm SURE that all the air behind this ball will be disturbed without an airfoil so a small one will be made. I opted against foam and glass for 2 reasons. 1, the weight difference will be only grams and 2, if the airfoil gets scratched, dinged, or rubbed off, it will be easy to fix not requiring glass work. Filler work will commence in the morning :)
