I finished deburring the bottom flanges of the spars and ribs and then dimpled the ribs and rear spar with the pneumatic squeezer. Once this was done, I broke out the Rustoleum again and primed the bottom flanges of the spars. I also primed the Z-brackets again. I used a small brush for all of the Rustoleum priming.
Bottom main spar flange primed and ribs dimpled
Bottom rear spar flange deburred, dimpled, and primed
