Had used expanding foam previous day to make the plugs in the aileron spars. Measured approximately 58 ounces of small lead shot for each side and got the ailerons balanced. Unlike the elevator, they don't easily stay level on balance, however you can tell when you have enough weight when they go either forwards or back from level with equal propensity.
I had missed spraying the top of the flap gap seals that go against the fuse. So primed yesterday and final coated today. Picture is of primed surfaces.
