This is especially helpful in the summertime when your car can reach over 200 degrees while sitting in the sun. Before tinting an aperture, you must clean the glass so that the film can adhere properly.
This will result in a professional looking tint job. Remove or tape back any flaps that touch the glass where it extends into your door.
You may have to remove the door panel. Alternatively, you may be able to tape back the flap with some tape.
Clean the window, both inside and outside. Use a solution of warm water and gentle soap.
A few drops of dishwashing soap or baby soap will work fine. Spray the glass and then scrape the water off with a fresh razor blade, taking care not to scratch the glass.
Remove the rest of the water and debris from the glass using a squeegee. Clean the squeegee after each swipe so that you do not transfer debris from one area to another.
The glass must be completely clean to get optimal results. The outside must also be clean if you plan on working or measuring the shade against the outside of the glass.
Spray the exterior of the aperture to be tinted with the detergent water. Allow it to dry completely.
Wet the exterior with your soapy solution. Lay out the film on the glass with liner side facing out.
Level the bottom edge of the liner with the bottom edge of the glass. Wet the liner side of the shade and squeegee gently to hold the film in position.
Line up the bottom edge of the shade with the bottom edge of the window. Make sure the film is covering the whole window.
Squeegee the shade onto the aperture gently to hold the film in place while cutting.
Carefully use the utility knife to cut off all excess shade.
Try to cut as close to the edge of the aperture as possible as the exterior will be the same shape as the interior. Peel off the film when done cutting.
Clean the interior of the window with the detergent water. Use the soft scrub pad to ensure all dirt is removed.
Use a squeegee to remove water from the aperture. Wrap the microfiber cloth around a credit card and clean under all gaskets around the window.
Liberally apply the detergent water to the interior of the aperture. Put a piece of tape on each side of the shade near a corner.
Use these tape pieces like handles to make pulling film from the liner easier. As you pull the shade from the liner, spray the film with the detergent water.
Align the top of the shade with the top of the window. Use the squeegee to push the film firm onto the aperture.
As you are pushing the shade with the squeegee you will work the water out from between the film and window. Move down the aperture applying the shade in this manner.
Wrap the microfiber cloth in the credit card and soak up any water that is along the edges. Expect that for the first 3 to 5 days after your tint is installed, depending on weather conditions, your windows may appear to be a bit hazy.
This is not an indication of a problem, but is a normal part of the drying process. Clean the inside of your apertures, which is where the tint is installed, with a special glass cleaner made for tint.
You can purchase this through the dealer who installed your car's tinting. Mix together a 50/50 solution to clean your car tint that is made up commercially available cleaner and water.
Use a soft cloth to wipe your windows clean to ensure you will not scratch the film. Keep the outside of your aperture clean with any kind of glass cleaner you desire.
Since tint is installed on the inside of the glass, it is the only area that requires special treatment. Do not roll your windows down when your tint is new until you are sure it is completely dry.
