I finished sanding the upper right transition piece and disassembled all the wheel fairings. I final fit each screw hole for size and depth and sanded the mating surfaces. After reassembling them, I applied a little epoxy/micro-balloon/silica mixture to the low areas and will sand it level tomorrow. I also sanded the nose wheel fairing at both upper and lower joint. Because this is where they are actually bonded, I left some of the seam and added the smoothing compound so it too could be sanded smooth.
