I have applied many sets of graphics and the best way to do it (as far as I am concerned) is this Lay the graphics where you want them. Hold one end, lift the other end and make sure that it falls into place correctly. Now, cut a strip out of the middle of the backing of the graphics. Place the graphics where you had them in step one. let the graphics drop into place. Now lift one end and peel the backing, smooth from the center. Do the other side the same way. Make sure that the plastic is clean and dry. I really don't think that the water and stuff is needed. I have never used it and have had about 9 successful graphics application experiences. Good luck.
