I deburred, deburred, and deburred some more - 2 hrs on the bottom wing skins. Not much to report. I removed the plastic, deburred both sides of each rivet hole, deburred the edges, and scuffed the inside for primer. Next step is to dimple, dimple, and more dimpling. 4 panels in all - left and right wing inboard and outboard sections.
Removing plastic (On the bottom I took it all off - see next picture)
