I worked on preparing the Spar and Nose Skin tonight for the Left Aileron.
The Spar: deburred all the holes, dimpled all the #40 holes in the flanges, and cleaned all the edges with 220 grit sandpaper
The Nose Skin: Deburred all the holes and cleaned the edges with 220 grit sandpaper.
Tomorrow, I will dimple the Nose Skin and then both pieces will be ready to be treated with Alumiprep, Alodine, and Akzo Primer.
