Applying Your Rear Window Graphics:

Remove the tape from the half on the perforated vinyl with no backing and bring it back to its original position, using a squeegee to smooth it down from the middle to all edges of the vinyl.
The squeegee should flatten the perforated vinyl securely against your chosen surface.
With the first half firmly applied and in place on the rear window, repeat steps 4 and 5 on the second half.
With the second half now taped down to the half that is already applied, remove the other half of the backing. Discard.
Remove the tape from the second half of the perforated vinyl, and bring it back to its original position, using a squeegee to smooth it down from the middle to all edges of the vinyl.
The squeegee should flatten the perforated vinyl securely against your chosen surface.
Use the razor blade to go around the edges, trimming excess or unwanted material from the window graphics.

Attaching Your Rear Window Graphics:

Clean the outside of your rear window.
Using the masking tape, tape the entire piece of perforated vinyl and its backing to the window (in the desired permanent position), with a piece of tape at each corner and one in the middle of the top and bottom.
Pick one side to start with, and tape the other side more completely to the glass so that it cannot move in any direction.
Next, on the side that you have not taped down more thoroughly, begin to separate the perforated vinyl from its backing, keeping the backing taped down.
Pull that one side of the perforated vinyl piece all the way across so that the entire piece is now folded in half on top of the side that is completely taped down. Tape it down with the other half so that it cannot move.
With the rear window graphics folded in half to one side, cut the backing directly down the middle and remove the half of the backing that was left taped down after the vinyl was removed from it. Discard of this piece of backing.
