The right rear spar was dissembled and all parts were deburred. The burraway tool may not be the magic I thought it was. It actually took longer to use it than using the hand deburr tool. Each hole took a count of 3 on each side and then I still wasn't completely satisfied with the results. Deburring by hand was twice as fast. I ended up deburring all the holes by hand. It actually didn't take as long as I anticipated. There's a lot of holes to deburr!
I cut some scotch brite pads into small pieces and stacked them up to make a buffing pad for the drill. This worked pretty well for buffing out the parts.
