I think you'd have a difficult time adhering a large decal around an entire tube, it could be done with lots of soapy water and extra good luck, but I think it's a big challenge to get it smooth, even and aligned. Far easier IMHO to spray the panel and then add the 2 stripes on the ends and 2 names to either side of panel: 4 separate decals. The "Seven 10" is a piece of cake, and a decal printer can make it a single decal with the black drop-shadow "booked" with opaque white script.
