Clean window well with soap and water. Do Not use window cleaner. Make sure all dirt debris and any foreign matter is removed from the window. Then clean the window with alcohol and allow to dry completely.
After cleaning the window thoroughly , place graphic against the window without removing the backing. You can tape the graphic in place on the vehicle. This will help you see the spacing needed for the location on the graphic.
Remove backing from the graphic. With help from an assistant place the graphic on the window in the center. Lightly apply from the center out to the edges. If bubbles appear stop, remove vinyl to the just past the bubble and re apply. Keep only light pressure on the graphic but be sure it is flat on the window as you go. Once it is on the window bubble free, using the felt edge of the squeegee, squeegee the graphic down to the window. Small bubbles can we removed by taking a pin and puncturing the vinyl to let out the air. Hard pressure is not needed just be sure the all adhesive is in contact with the window. The edges will be trimmed next so it doesn't need to be flat near any areas that are raised above the glass, such as molding or trim.
Cutting around window hardware:
Remove the wiper arm mounting nut cover and remove wiper arm. If wiper arm is hesitant to be removed, a inexpensive removal tool can be purchased. As the graphic is being installed and approaching the wiper arm mount, cut a slit to get the graphic over the arm mount. Trimming around the wiper arm mount and glass strut mounts can be done with a snap knife cutting as close to the object as possible.
