Using the spray bottle with the cleaning solution wet the exterior of the rear window, clean as you would for a normal installation prior to cutting your pattern. Split the trash bag* down one side and across the bottom. Unfold so that you have a single large piece. *It is important that you not use a thick trash bag, the thinner the better so the bags can me formed to fit the window more easily. Wet the exterior of the rear window again. Cover the exterior of the window with the large opened piece of trash bag. Smooth the bag on the rear window to remove creases. Trim the bag to 1" larger than the black border to cover the complete window. Take the trimmed bag into the rear of the vehicle, and place on the rear deck. Much as you would when preparing to install window film. Spray the interior of the window with your cleaning solution. Wet the window again with an ammonia and water mixture of 2/3 water to 1/3 ammonia (use a mask for ammonia fumes if needed). Place the trash bag over the interior of the rear window. Tucking it in as much as possible around the rear deck etc. Almost as if you were installing the bag on the rear window. Park the vehicle in the sun with the rear window facing the direction in which it will receive the most sun based on your location. Leave the vehicle in the sun for at least 30 minutes while trying not to allow the ammonia to evaporate. After 30 minutes, starting in a top corner, peel the film and the bag away from the glass. If the film peels in layers (delaminates) stop and repeat the process from step 8 to 11 and check again in 30 minutes. Once film is removed re-mist interior of rear window and scrub off any left over adhesive using a white scrub pad or 000 steel wool. Be careful when scrubbing on defroster lines. Wipe off moisture and clean the window with your cleaning solution, to remove all traces of the ammonia mixture. Helpful Tips: • Have the customer bring in the vehicle on a hotter day, if possible. • Remember to remove the brake light before you cover rear panel or use ammonia mixture. Point to Remember: It is imperative to get the ammonia mixture off the window, ammonia and window film adhesive do not play well together. If ammonia is on the window when you perform your installation you can almost guarantee you will be seeing this automobile again in a few years or so.
