Ok, so I just sold a machine and pulled it out of my line up. After I pulled out it out, I looked over to my KISS Pro (purchased NIB) and noticed wrinkling on the side around the bolts. Upon further investigation, it appears the artwork has shrunk by about 1/8" - 1/4" on the three visible sides. When you look at it, you can see the difference and when you run your finger over it- you can feel a sticky residue.
So my question is "is it common for the decals to shrink and wrinkle like that in a normal temp controlled environment? If so, is there anything that one can do to prevent it shrinking further?"
