The covering worked out fairly well for me, following directions helped. Outlining areas with a trim iron at high temperature, sticking down edges, was the start. Followed by going over the entire plane with a full sized iron, sticking and shrinking covering as needed. I used a heat gun to tighten bays, aiming the gun so that wing bubbles were blown to the bays, as much as possible. On solid sections I went over the entire structure, first outlining kote edges, then shrinking up middle. When necessary I used the point of a #11 to release trapped air, sealing over the puncture. When finished almost all of the imperfections looked decent. The rudder/fues trans wouldn't seal down, left it alone. So far no covering has lifted. A black outline stripe on the canopy loosened and flopped off. Can be easily replaced. Also a thin white stripe pulled off and was lost. Maybe 25-30 flights so far. Big problem was the soft ply on the nose. Lead to major vibration issues discussed on the PF fp40 thread. When plane first went to the field the PF got lots of compliments. Even at Brodak people thought enough of the plane's looks to make positive comments. Plane looks somewhat cruder now, mostly because of the nose vibe issues and the various fixes tried. Also had to cut into the wing covering when the bolt holding leadout guide worked loose and came out. Watch out for that. Your parts bin may not have the right metric bolt. Setting up a Cardinal required a similar covering drill.
