Should I Accept the Car Film Provided by the 4S Store?
4 Answers
Yes, you can accept it. The car film provided by the 4S store is of good quality and can be safely used on your vehicle. Applying film to the car windows helps protect privacy and enhances the overall aesthetic appeal of the car, especially with darker-colored films. Here are some precautions to take after applying the car film: 1. Do not roll down the windows: After applying the film, it hasn't fully adhered to the glass yet, so avoid rolling down the windows for three days. 2. Do not wash the car: Avoid washing the car or wiping the film with hard objects for three days. 3. Water bubble phenomenon: On the second day after application, it's common to see water mist or bubbles, which is normal. The moisture will evaporate after exposure to sunlight. 4. Winter application: If the film is applied in winter, avoid rolling down the windows or washing the car for a week. Moisture evaporates more slowly in winter; the front and rear windows may take a month to dry completely, and the rear window heating wires should not be used for a month.
When I bought my new car, the 4S dealership gave me window tint as a freebie, but it started bubbling and peeling within a year, with poor heat insulation. Free stuff usually has low quality—they probably used it as a promotional tactic to clear inventory or lure you into follow-up spending. My advice: Always ask about the film's brand and specs like heat rejection rate and visible light transmission (VLT). If it's a reputable brand, fine, but most free tints are basic models. Test it simply by shining your phone's flashlight through the film to check clarity. Don’t shy from negotiating—try swapping it for more valuable perks like maintenance vouchers. Quality tint affects summer driving comfort, and cheap ones may even compromise visibility and safety. Putting in effort upfront beats regretting it later.
Last time I bought a car, they also threw in window tinting, and I went with it to save money. After installation, it seemed okay at first—saved me a few hundred bucks—but later I realized the heat insulation wasn’t strong enough. Driving under high temperatures still felt uncomfortably hot. I’d suggest checking the tint’s reviews or user feedback on the spot; a quick online search will give you an idea of its reputation. The film 4S shops offer is often the most basic version—you can negotiate to upgrade by paying extra for a premium version. If you’re on a tight budget, accept the free option but watch out for warranty periods that are too short. Remember, poor-quality film can cause window blurring, affecting driving safety—don’t just chase small savings.
The quality of free car films provided by 4S shops varies greatly, so don't rush to accept them. Ask them specifically what kind of film it is, and don't just listen to their sales pitch. Test the light transmission yourself with a simple tool like a flashlight. Poor heat insulation film turns the car into an oven in summer and wastes air conditioning electricity. Consider whether it's worth taking the free option, as poor quality may lead to higher replacement costs later. Read more user experience shares before making an impulsive decision. Good window tinting is important for protecting privacy and reducing UV damage to the car in the long term.
