Scuffed and alodined all stiffeners. The Touch-n-Prep pen worked great! I also realized that I’d neglected to match-drill the trim servo mounting plate to the left elevator skin, so that got done today. I then deburred, dimpled, scuffed and alodined it. I also forgot to take any pictures. Even if I had, they would be pretty boring…you’ve seen one stiffener, you’ve seen ’em all.
