Put about 2 to 3 drops Dawn dishwashing liquid (yes, Dawn; more soapy stuff) and a capfull of alcohol in a cheap garden sprayer filled with warm water; Shake. Spray the LETTERS LIGHTLY; hold the sprayer back about a foot and mist it on, just enough to call it wet. Slide into place, squeegee the excess water out. The alcohol evaporates quickly and allows it to adhere faster than just soapy water.
In case any of you have to add decals to glass - NEVER, EVER use water & soap; apply them dry. You'll be there for a couple of hours waiting for the water to evaporate.
