Should I use the wet method?
(This method should be used only on windshield applications, unless you have installed decals professionally.)
Mix a gallon or so of water with a few drops of dishwashing liquid. Use a spray bottle and wet the area where the decal is to be applied.
Trim away the transfer tape so that the tape is about (within 1/2") border, of your Decal. Remove the backing paper the same as the Dry Method instructions and place the Decal, still attached to the transfer tape, to the thoroughly wetted surface. The decal can then be gently moved and repositioned correctly. Your Decal will slide on the thin film of solution trapped between the vinyl decal and the surface. If you are doing a windshield decal and need to curve the letters, cut the transfer tape with a pair of scissors between the letters about 3/4 of the way from the top of the Decal and position the letters where needed. DO NOT cut all the way through as this will mess up your spacing between the letters. When the decal is in the final location, use a small squeegee or drivers license to squeeze the water and detergent solution out from under the decal. The transfer tape will protect the decal during this process.
Be sure to squeegee as much solution as possible from under the decal. Take your time, because if not enough solution is removed from under the decal, the Decal will not adhere to the surface enough to allow the easy removal of the transfer tape. Although a squeegee is the recommended tool, the water can also be removed by using your fingers, or a soft cloth. When through with the squeegee, the transfer tape can be carefully removed. Work the decal with your fingers, and a soft, absorbent cloth around the edges and corners to remove any remaining solution. Warm weather is best for this application. If there are bubbles present under the decal that cannot be removed by working them to the edge of the decal with your fingers, then a small pin or needle can be used to puncture the decal at the bubble, to remove the air. A small pin hole will not be seen after the air bubble has been worked out with the fingers.
