I used the middle one....3M 77......spray THIN, let tack up a few minutes, following instructions (glue tacky to transfer), and carefully align. I was able to remove and reposition to fix a mis-alignment. Tip, practice the wrap BEFORE you apply glue. Trim the tunnel areas, so the wrap will follow the curve of the body tube, otherwise, it will cause a flat spot and not lay down. After the 3M dried, I reglued all the seams with liquid plastic cement. I tried some CA and kicker on the areas that lifted, but I found the plastic cement worked better.
