cpcat, the two things that help me apply those decals is windex and a credit card. In order to get the decal straight, lightly mist the windex on the back of the decal (with the back paper removed) and loghtly mist it on the glass of the boat where you are going to place the decal. Put the decal on and the windex allows you to slide the decal around so you can place it right where you want it. Then take the credit card and smooth out all the bubbles. Make sure you hold the decal so it doesnt slide around. Then you have to let the decal dry for 3 hours or so, so that the windex evaporates from between the adhesive and the glass. After some time, slowly pull the paper away from the front side of the decal. Hope that helps. Chip
