De-burred the holes, sanded the edges, and scuffed the R/H wing nose ribs 1-5, trailing edge ribs #1 and the three small ones that go by the gas tank, the 4 Fwd and Aft rib stiffeners, and the 5 flaperon arm L angles. Primed the mating surfaces with the epoxy primer. The ribs that the flaperon arms attach to I primed the entire rib.
