applying static cling

• Spray on some plain water.
• Position decal on glass.
• Spray more water on the decal for lubrication.
• Squeegee using a soft rubber window cleaning squeegee.

 

+1 to what Fred said.

Also if for any reason you need to remove the static cling while it is still wet. DO NOT lay it down on the liner paper! Some, not all, liner paper will stick like glue to wet static cling, don't ask how I know. Soaking it in water for a very long time will help loosen some of the paper enough to disintegrate and float away, but not always all of it!

 

Try using a regular squeegee. You know, the kind you use to wash your windshield at the gas station.
