I cleaned the fuselage tubes, wiped them first with Poly-Fiber Cleaning Solvent, then MEK, and applied anti-chaffe tape. I removed the upper flap pulleys, and made a small wedge of epoxy-covered balsa to transition the door post channel to the upper tubing. I don't want to cover the sections of the fuselage immediately above the windows, so I was afraid the transition there would be too sharp, risking cutting the fabric with use.
Flap pulley was removed and a balsa wedge fabricated.
