As a Sign Painter and Long time sign & graphics man, I fully agree Putting on Adhesive backed Wraps is akin to applying Vinyl lettering and graphics
Use of a wetting agent and squeegee will produce precisely aligned, parmanently attached wraps.
I've used this technique with every kind of adhesive backed material i've run across with 100% fine outcomes, It's even been done on unpainted Estes style body tubes without harm to either the tubes or wraps.
Start by wiping down the entire finished model with a tac-rag to remove any and all dust and debris.
Remove the backing from the adhesive backed wrap, laying it adhesive side up on the clean table surface. mist spray a complete coating of wetting agent on the entire wrap and the premarked portion of the surface the wrap is to be applied. carefully attach the wrap to the starting alignment line and letting the weight of the wrap lay the vinyl completely around the body. If for some reason the ends don't align, simple lift the wrap, reposition and try again. Once happy with the alignment use the squeegee to work from the center of the wrap out to the edges, all the way around the tube. this removes as much of the wetting agent liquid as possible and removes just about any bubbles that may appear. If you come to a spot the doesn't look right, before squeegeeing re-lift and re-align as needed. this usually isn't necessary. Once the entire wrap has been squeegee'ed into place. set the model aside for at least an hour or two. After this time re-squeegee the entire wrap to complete the adheasion process.
Heres a pic of the wetting agent I and most sign people have been using for many years. You can buy Vinyl application liquids but why when a couple drops of dishwashing liquid in a pint of water work just as well

Hope this helps.
