Used the squeezer to dimple the screw holes on the join plate. Used the dimple to align a nut plate and match drilled the mounting holes for the nutplates. Set up the C-frame and dimpled the leading edge skin. Used my flange starightening tool as an extra hand to keep the skin out of the way. Washed all the leading edge parts with warm water and Dawn dish soap and set them out to dry. Once they were thoroughly dry, I set up the paint table and shot all the parts, as well as putting a line of primer on the inside of the skins for each rib.
