I was thinking of buying this: http://www.crazypc.com/products/82302.html for my cm 690 that I have. The thing is, I don't have a window. Can I still apply this using the method of spraying a mist of water and applying it?
The applique is vinyl according to your link, so it should work. Just be sure to clean the side panel's surface in accordance with the directions. If the side panel is not very, very smooth, the applique may not stay attached.
