Switched back from working on the Vertical Stabilizer to prepping the Horizontal for primer. Lots of deburring, dimpling and scotchbriting. I had also forgot to drill the trim cable hole in the front left spar, so that was done as well.

More of the ribs after being dimpled and hit with a quick pass of the Scotchbrite pads.

I’m going to take the parts home from the hangar so I can prime them.
