the film is very thick, which facilitates draw a bubble free. It is positive that it does not require an adhesive. Simply spray the window with water and paint film smooth with a rubber spatula. Since the separately ordered rubber spatula was Nocht not delivered and we did not want to wait, we have a window-puller used with rubber lip. Went just as well.
