If you use the windex method, spay it lightly with original windex, take a paper towl and spead the windex around. Lay the piece on the windex and then use a credit card to carefully worked out the bubbles. DO NOT try to iron while the windex is still wet. It will bubble up immediately. Wait a couple of days and then set your iron on low and just lightly go around the seams. Don't try to iron down the whole peice. Here is a picture of my 1/4 Cub that I am in the process of covering now. Using the windex method. The other picture is Big Bingo wing, top and botton also using the windex method.
