Can the Car Film Provided by 4S Stores Be Used?

If it is some low-quality car film, it is better not to use it. If it is a product from a reputable brand with good quality, it can be used. Nowadays, many 4S stores offer gifts to customers after purchasing a car, such as floor mats, car films, and some car electronics. It is essential to carefully check whether the floor mats, films, and other products provided by the 4S store are high-quality and compliant. If they are inferior products, it is better not to install them in the car. Inferior films and floor mats can release toxic substances, affecting the health of passengers. Moreover, poor-quality films can significantly compromise driving safety, as their light transmittance does not meet standards, which can be hazardous during night driving. Inferior films also fail to block UV rays and provide heat insulation, accelerating the aging of the car's interior when parked under direct sunlight. It is recommended to purchase a high-quality film from a reputable brand after buying a car. Good-quality films can provide heat insulation and UV protection, safeguarding the car's interior. Additionally, premium films last longer and do not release harmful substances. High-quality car films have excellent light transmittance, ensuring safe night driving. When applying the film, it is advisable not to install it on the front windshield, as the windshield already has UV protection, and applying film there can impair driving visibility.

I've been driving for twenty years, and every time I pick up a new car from the 4S shop, they give me free window films. I think they're completely usable, but don't expect anything too high-end. Those free films are usually basic models, with decent UV protection and heat insulation—enough for daily sun protection. However, after two or three years, they tend to bubble or fade, which not only affects appearance but also visibility. The key issue is the installation quality. The workers at 4S shops may lack experience in applying films, leading to bubbles if not applied properly or misalignment that looks unappealing. But since it's free, it's a money-saving option for now, and you can consider upgrading to professional films later for better durability. On a related note, it's better to choose light-colored films for higher safety—don't go for dark ones just for privacy, as they can be dangerous when driving at night. Overall, they're fine as entry-level options, but don't expect them to last too long.

The car film provided by the 4S shop when I got the new car is usable, with an average effect. It's okay for heat insulation, quick to install but poor in details, and the edges were not well applied, causing wrinkles within half a year. Related topics are types of car films; the basic model given for free may not be durable, while professional ceramic films are more expensive but last longer. It's fine to use the free one for now to save some money, and replace it when it's damaged, as it doesn't affect daily use.
