Flipped her over! I sanded and acetoned the top of the right wing in prep for Filler. The Top looks much better in contour than the left so this may very well be a 1 coat and done deal. 9 cup fulls of filler or almost 1/2 gallon and the top side is filled pretty thick. Saturday will be a day of glorious sanding.
Update: The right wing rudder is sanded and ready for primer. The 1 skim coat worked great and the other side is free of pin holes and has a great contour. good times :)
