More Wing Skin Prep

I finished deburring and dimpling the left inboard top main wing skin.  You can see the four closely spaced rows of rivets near the top of this picture.  These are for the ribs in the wing walk area.  It's taking me about 90 minutes per wing skin to remove the plastic, prep the edges, debur both sides of every hole, and dimple.  Since there are eight main wing skins total (two each on the top and bottom of each wing), I figure it will be about 12 hours total of this kind of work to get all of the wing skins prepped.  I really understand why people say the wings are boring.
