Installed 1" tapes over the ribs of the elevator. Instead of buying 1" tape I used 4" tape and cut it down. I initially tried using a knife and a 6' straight edge but it was difficult to keep the cut edge straight. I tried wrapping the tape around a solid round object then placed a razor knife blade in a small sheet metal brake as you can see pictured. You can adjust the width of the cut by adjusting the metal flat stock seen in the picture.
The tip of the blade is in the middle of the blue tape.
