Almost finished port F-970 riveting. Last double-row completed and under seat pan and baggage floor rivets were done. Besides a few mal-bucked rivets, left the rivets around the curve where F-970 joins the bottom skins open. There is a gap between the tabs of the rear fuse skin and F-970 that will take spacers to fill in. Primed brake pedels with Rustoleum flat grey metal primer. Just roughed the surface up a little, then wiped with MEK to prep.
