Brief Description: Prime Left WingTop Skins and Countersink Spar
I set up the paint table and primed the mating surfaces on the inboard and outboard top skins.
There are holes in the spar and forward end of wing ribs that have no rivet callouts or mention in the plans. As I researched these in the VAF website some builders called them the "mystery rivets". I concluded that since there are corresponding holes in the spar and ribs, these must be riveted. I drilled the holes to #40 and deburred.
I also continued to countersink the spar for the skins.
