Started work on the fairings on and off over the last few weeks. Today was the big day to actually mix some epoxy and do some filling and sanding. Starting with the rudder fairings, I match drilled the fiberglass fairings to the rudder. They fit pretty well, but I'm following the procedure in chapter 5 to sand back the edge of the fairing along the seam and fill it flush to the rudder with flox. Wrapped the rudder in clear tape and cleco'd the fairings in place. Then mixed some epoxy and flox and smeared it across the joint. Also used flox to build up the front of the top fairing to align with the counterweight better. Tried to minimize the amount of flox since it will be tough to sand. Seems like some use micro for this step, but I really want the new edges to be durable. Let it cure for a few hours and started sanding. I removed one cleco at a time to compromise between holding the fairing tight to the skin and providing some room to sand. 80 grit with a small wood block wasn't too bad to get through the first pass of sanding along the joint. Then removed the fairings and sanded the remainder of the flox smoooth. Replaced the tape on the rudder skin with fresh tape, reinstalled the fairings and then slathered on a micro mixture to get the first pass at smoothing out pinholes and touching up any low spots along the seam. I'll let the micro cure over night and sand tomorrow. Trimmed and match drilled one of the elevator fairings too.
