More deburring wing skins. Not as bad as deburring ribs but still boring. Completed deburring the last lower skin (left lower outer skin W-1203-L). Completed deburring left and right upper outer skins W-1203B-L & -R. Also completed deburring both upper left and right mid skins W-1202B. All that's left is the upper inner skins W-1201B-L & -R. Should be able to complete those tomorrow night and start prepping to prime inner surfaces of skins.
