Is it necessary to apply rear window film?
2 Answers
Applying rear window film is necessary for the following reasons: 1. Cooling: It provides heat insulation and blocks UV rays from the sun, which can also help reduce air conditioning consumption to some extent. 2. Privacy: It ensures a certain level of privacy inside the car. Typically, cars with window film make it difficult to see inside from the outside while allowing clear visibility from the inside out. Post-application precautions include: 1. Sun-drying the vehicle after application: Whether it's the front or rear window, after applying the film, it's advisable to expose the car to sunlight for a period to help the film dry faster, ensuring it doesn't affect subsequent use. Generally, about a week of sun exposure is sufficient. 2. Avoid rolling windows up and down: After applying the film, try not to roll the windows up or down for at least three days. This is because there may still be moisture between the film and the glass, and rolling the windows during this period can cause the edges of the film to peel off. 3. Avoid attaching items to the windows: For one month after application, refrain from attaching strongly adhesive labels to the window film to prevent partial peeling.
As a parent who frequently drives my family on outings, I firmly believe rear window tinting is absolutely necessary as it significantly enhances both safety and comfort. Without tinting, strong sunlight directly penetrates through the rear windows, exposing passengers to harmful UV rays that can damage skin and cause discomfort for children and elderly passengers. After installation, the tint effectively blocks over 90% of UV rays and heat, reducing cabin temperature by at least 5 degrees Celsius – this eases AC workload and improves fuel efficiency. Most importantly, in case of accidental collisions, the film prevents glass shards from scattering, providing an additional layer of protection. Having used rear tinting on my own vehicle for over a year, I've experienced noticeably cooler cabin temperatures during summers without compromising AC performance, plus the interior color hasn't faded thanks to the film's excellent durability. I recommend opting for mid-range light transmission films – they're reasonably priced, DIY-friendly to install, and above all, prioritize safety which should never be compromised.
