I dimpled the holes in the j-bar wing skin stiffeners and prepped them for painting (wash with soap and water followed by acid etch). I also prepped the flanges of the spars for priming. I only washed and scrubbed the flanges with maroon pads. I didn't acid etch because I didn't want acid getting between the layers of the spar. I finished off the day by masking off the spar flanges.
