I used my DA sander and 40 grit to remove overhanging plies and taper them back to prepare the landing gear hoop for the leading edge laminates (4 my plies of uni). I wend over the rest of the leg lightly with 80 grit even though I had peel plied a lot of it. Set the hoop back on the table and used dabs of Bondo to affix it to the three stand-off screws.
