With the help of my girlfriend I completed the dimpling of the HS skins. The last 2 center holes closest to the leading edge where done with a close quarters dimpler and some very slight machine countersinking to get the rivet to sit flush.I also scotch brighted the edges and used 600 grit wet sandpaper to further smooth out all edges.Priming the rivet lines and re-touching the ribs and spars is next up.
