"Eliminating air bubbles Press clings firmly from center out to eliminate air. Sometimes after you apply them it takes a while for the sun to cause air to evaporate out from behind clings. Small bubbles that stay can be popped out with a needle and pressed down. For a professional look or for applying very large clings you can paint on a layer of clear background paint to the back of the cling and then press it to the window, pressing the air from the center out. Work quickly before paint dries, wipe or scrape excess paint off window, unless you are going to do a textured paint background anyway, then you can paint the rest of the background over it."
