Automotive window tint film is a triple-layered sheet of adhesive, metallic particles and shade pigment. Often, the tint can become damaged from scratches or tears, and must be repaired. Tinting wth large tears or air bubble damage should be replaced, not repaired. The average backyard window tinter can complete the repair of a small section in about an hour.
Locate the area of the tint damage and cut a line through the material around it, preferable in a square shape, with the razor blade. The line should be firm and clean and should go through to the glass. This isolates the damage.
Spray the area with water and dab any excess. Pry up one corner of the cut section with a razor blade, and be sure to get both plastic layers of the tint pulled up. Push the razor into the edges of the section, working the tint up from the glass carefully. Spray the section with more water if it begins to dry. Once the section is more than half raised, try lightly pulling on the tint section to peel it off.
Wipe the uncovered glass section with water and allow it to dry for a few minutes. Get the excess glue off with the razor, especially around the edges. Do not use an ammonia-based cleaner, because this will damage the surrounding tint.
Cut a section of tint that is a little larger than the section removed from the window. Spray the window with water again. Peel the backing plastic from the tint film and quickly place it to the glass, glue side down. Position it quickly before the glue adheres to the glass.
Squeegee out the air bubbles, starting from the centre of the section and working toward the edge. Spray more water if the tint begins to dry.
Once the air bubbles are removed, cut the tint at the edges of the section, as closely as possible to the edge. The closer you get this cut, the more seamless the repair will appear. Slice the edges from the new tint film, and the section will be repaired. Allow to cure for 24 hours before cleaning.
Do not peel the new tint back off and try to "start over." This will ruin the tint film and glue.
Tint the window in a ventilated environment since the glue can be pungent.
