I took the 34 bolts out of the right wing root,which consist of (4) backing plates, 2 hinge knuckles, and a steel root, all of which bolt to the wing spar, an aluminum I-beam. A lot of scrubbing, degreasing and etching priminer. All signs of rust, chipping paint and grease are gone. Will order new hardware (bolts, screws and washers) to replace originals before reinstalling with torque wrench.
