Brief Description: RH wing spar - completing tank attach nutplates
Finshed the counterskinking for the lower RH spar tank attach nutplates, then riveted the nutplates in place.
The countersinking for the #8 screws has removed the corrosion protection from the spar where it has been cut away, so a drop of Alodine on a cotton bud was applied to each one to replace that protection.
