Some base tapes will soak up the first coat of glue and they will want another. My recent Vittorias in both Rally and Corsa models required just one coat. I followed Continentals gluing instructions once. Never Again will I glue a tire on that well unless I'm going for a world record on the track.

Stretch the tire upon installation from the very beginning at the valve. If that last bit is much harder to get over the rim, start over and stretch harder from start to finish. You will not want that flat spot that results from over stretching that last section. I doubt you can feel it on the road but you can see it in the stand and that bugs us.
