Inside Back Window Glass;
Spray the inside of the glass with soapy water and scrub it with a white abrasive dish sponge, paying extra attention to the edges and the dotted areas. (Use a white dish scrubber, not a green one, as it will scratch the glass, or use Steel wool with 0000 grade.) Squeegee the glass dry and wipe the dotted edge with a shop paper towel to lift up the black residue the ceramic edge gives off, (This will help the film to stick to the dots.) Spray the window again, and squeegee carefully to remove the water. Now flush the window from the top down, avoiding the very top and the dots, if the window has them, to prevent dirt from bleeding.
Now, face your wet cutting glass surface. Carefully remove the liner from the film without it lying over onto itself (if the dry adhesive surface touches itself, you will need to start over as it will stick firmly). Liberally spray the adhesive surface with the solution as you remove the liner to protect the adhesive.Â
Carefully climb inside the vehicle with your film outstretched in your arms, ensuring it does not come into contact with any other surface.
Apply the film using the same steps as for roll-up windows. Secure the film to the glass by anchoring the film at the center point of the glass and squeeging the film to the outside edges.
Always use long consistent strokes applying pressure to squeegee out water trapped between film and glass.
An Additional Option for How Windows are Tinted but NOT necessary.
Before applying the film, remove the rear deck and brake light IF NECESSARY!
This can help with the installation of rear window film. The back window is a large piece of film that can be awkward for a novice. Make sure you do not touch anything but the clean glass with the film, it’s not that easy, and if the felt from the rear deck is against the glass, the film will be challenging to reach and squeegee completely. Most cars only need to have the brake light removed.
Black Ceramic Dots:
Most newer cars have black ceramic trimming on the edge of the rear window.
Sometimes this ceramic has a straight edge and sometimes a dotted edge.
Usually, this dotted edge is only 1/4 inch wide or more, depending on the make and model of the vehicle. The window film usually won’t stick to these dots flush, so a pocket of air will trim the glass. On most cars, this isn’t very noticeable.
The problem is that some cars have a six-inch wide band of dots on the upper edge of the back window. If that is the case, the air pocket created is so large and uneven that it is very unattractive. The film does not have flexibility (too rigid, depending on the quality of the film.) One solution to the matrix dots is to apply black vinyl to this area.
