I have recovered two (2) ARFs without removing the control surfaces. Both of them have pin-type hinges similar to the Robart hinges. I cut trips about 3/4" wide at a length just longer than the distance between the hinges. I then notched the ends of the strip for the hinges, slipped the strips in the gap, and ironed them down. At the hinges, the strips had a slight overlap. When all of the gaps were covered with the strips, I completed the covering beginning with the primary covering layer overlapping the strips. Even with close inspection, it is difficult to tell that it is not done with a single piece.
