3 hrs. over the last 2 days filling rivets and flipping the right wing.

After the taping, sanding through the tape to expose the heads, smearing Bondo across the heads, drying and then sanding the heads, pulling off the tape reveals this (I also cleaned the surface with my Extreme Simple Green solution).  Nice!:

Long view down the wing.

My friend David came over to help me flip the wing.  Thanks David! ;-)

NEXT SESSION:

1. Make sure the jig ends are perfectly level with each other and secure tightly to the bench.
2. Start the prep of the top skins.
