It seemed that the filling and sand cycle would never end, but all good things must come to an end and so did this task. A few coats of high fill sandable primer and touchup with bondo scratch filler and I was finished with this piece. I know there will be another final touchup session before final paint goes on, but this is it for now.

The rear skirt took an equal amount of effort to get to this stage of completion. I have yet to Sikaflex it into place (the black tape is the forward edge of the glue line) and flush rivet where it is attached to the canopy skirt. The fit between canopy and fuselage skin is great. Thanks to Bret Smith for his great building blog http://www.flightinnovations.com/ and ideas for completing the canopy attachment sequence.
