Can the free car film be applied?
2 Answers
The free car film can be applied. Here are the precautions after applying the car film: 1. Do not roll down the windows: After applying the car film, the film has not fully adhered to the car glass. Do not roll down the windows within three days. 2. Do not wash the car: Do not wash the car within three days, and do not wipe the film with hard objects. 3. Water bubble phenomenon: On the second day after applying the film, water mist and bubbles usually appear, which is normal. The water will evaporate after exposure to sunlight. 4. Applying film in winter: If the film is applied in winter, do not roll down the windows or wash the car within a week. Water evaporates more slowly in winter. The front and rear windows need a month to dry completely, and the rear window heating wires cannot be turned on within a month.
The free car window film can be applied, but as an average car owner, I have some concerns about its quality. Free films are usually low-priced and of average quality, with potentially poor light transmittance, making it hard to see the rearview mirror at night, which could lead to accidents. Bubbling and fading are common issues, especially under high summer temperatures—thin materials may not last a year. I once applied a film from a 4S store, and within three months, it was full of bubbles. Eventually, I paid to replace it with a branded film, which felt safer. Installation matters too—the technician’s skill is crucial. My advice: try the free film first to see how it performs, but don’t expect perfect heat insulation or UV protection. Be prepared to replace it anytime. After all, driving safety comes first—it’s worth spending extra to ensure clear visibility.
