Do not use too much spray adhesive or your art will shrivel. The Tron sides were just not sticking. If the machine was standing up, the art would curl and peel off the sides. Time for additional adhesive!

We bought the 3M Spray Adhesive 80 as recommended. I practiced a smooth spray motion. Sprayed the back and smoothed into place. A few moments later we had great looking art. A few moments after that we had destroyed $90 of Tron Side art.
