October 14, 2015 – I started prepping the top skins for installation.
I removed the blue film on the rivet lines, and completely on the interiors.
I deburred the edges and the holes, and scuffed the interior surfaces to prep for paint. Then I dimpled…
I also had to dimple the j-stringers, and I countersunk the reinforcing plate that goes under the skin at the forward end.
Time: 2:40
