If you keep the wiper clean at all times you should be okay. Ask the vinyl shop to use hi performance cast vinyl. its thinner than calendered and you will have less problems. Also, dont wet apply it on glass, its too much of a [censored] to work with. fold the sticker in half, mark your center with a pencil, then tape the sticker to the window, with 2 small pieces of tape. Center it and level it. Then apply a strip of tape in the center top to bottom. Peel back the backing off, up to the tape and cut it. Now slowly squeegy the decal down starting at the center and work your way the the edge. Squeegy top to bottom. Now take off the masking tape and do the same for the other side. remove the transfter tape, and you should be bubble free, centered and level!
