Directions should read:1. Open box2. Place contents in trash.I've applied plenty of vinyl coverings to glass. This stuff is good only for a waste of time. Backing adhesive is too sticky, film sticks to itself and pulls its own adhesive backing apart, leaving you a "marbled" texture on the glass. Not so attractive. A good example of a product made with very little testing, in my opinion. Save your time and a headache and buy a better brand.I almost left out the best part! I bought two boxes. The first box I opened, the film had a big "x" cut right in the middle of it! Thanks Gila! Barf.
