Is It Troublesome to Apply Car Window Film for the Second Time?
2 Answers
Applying car window film for the second time is relatively troublesome, especially for older cars that have been used for a long time. A significant amount of dust accumulates in the gaps of the glass, and the removed film usually leaves adhesive residue. Cleaning the leftover adhesive can create debris, which affects the cleanliness required for the new film application. Introduction to Car Window Film: Car window film involves applying a thin layer of material to the front and rear windshields, side windows, and sunroof of a vehicle. This layer is also known as solar film or heat-insulating film. Functions of Car Window Film: Blocks ultraviolet (UV) rays. Medium and long waves in UV radiation can penetrate thick glass, but applying heat-insulating film can block most UV rays. This helps prevent skin damage and reduces the aging of car interiors.
The second time applying window film is more troublesome than the first. The main issue is that removing the old film takes a lot of time, especially on the rear windshield—if not done carefully, the heating wires can get damaged. Last time I replaced the film, the technician spent nearly two hours just cleaning off the old film and adhesive, leaving the glass covered in sticky residue. After cleaning, the glass must be thoroughly dried, or else the new film may bubble. Additionally, the window seals can get loosened during the removal process, so it’s best to have the technician check if they need replacement. The cost is about 100–200 RMB more than the first time, mainly due to the adhesive removal process. It’s recommended to choose a professional tinting shop, as they remove old films more efficiently without damaging the glass components.
