On the next one, run a piece of tape along the top of the sticker and the glass 50/50 split, measure to make sure it is straight, lift the sticker up all the way and peal the backing paper off the sticker about 1/2 way down, start applying it to the glass and work your way down slowly until it is all on,
use lots of water and press hard to get rid of the water and air.
if you know the guy printing the sticker ask him to do it on 3M controltac 180
it has a cross hatch pattern on the back and it is real easy to install and you don't need to use water.
