After prepping the mid-bottom skins, I decided to do the same for the forward-bottom skin. I deburred, dimpled, and primed the skin. I was going to back-rivet the floor stiffeners on, but I wasn't especially happy with the reults on the first few rivets so I stopped. I may give the back-riveting another try, but I will probalby end up setting those the traditional way.
I then fitted and clecoed the skin in place. There are a few places I want to roll or tweak the edges to eliminate gaps, but for the most part it looks good.
Have to remember to include a pic of myself for the inspector
