Rear Window Cleaning and Prep

You want to prepare and clean both the outside and inside rear window before film application. The outside window needs to be prepped and cleaned because you will use that side to cut your film pattern. Obviously, the inside rear window needs to be extra clean to eliminate any contamination that could damage the film.
