RE: Graphics
If you are still looking for an answer, try soap and water. Add a drop of dish detergent in a spray bottle of water. Spray both surfaces, place your graphic on the aircraft, move it around to where you want it . Take a squeeze and remove as much water as you can, allow it to dry in the sunlight if possible, wait about 10 - 24 hours before moving the graphics. Once completely dry it will not move.
The soap and water trick is also use to put tint on car windows. It works great.
Good luck.............
