What brands of window films are available at BMW 4S stores?
2 Answers
There are 3M, LLumar, Aileisi, and Kanglixin. Precautions: After applying the car film, avoid rolling down the windows for three days, do not wash the car for three days, and for vehicles with sunroofs, do not open the sunroof while driving, especially at high speeds, for three days. Winter film application: Do not roll down the windows or wash the car for a week. The front and rear windshields take about a month to dry completely. During the day, the front windshield should face the sun. Most importantly, do not turn on the rear windshield heating lines for a month, as using the heating lines after applying the film in winter can cause bubbles near the heating lines, which are irreparable and may lead to unnecessary losses and troubles.
Last time when I accompanied my friend to the BMW 4S store for window tinting, the staff introduced several popular brands in detail, such as 3M and XPEL, which are all internationally renowned brands with excellent heat insulation effects and UV protection. I personally witnessed them using professional equipment during installation, being very meticulous to ensure the film fits the car windows without any edges lifting. Actually, the brands cooperating with the 4S store may vary by region and inventory, but they always guarantee original factory certification to avoid counterfeit products. Although the price is a bit higher than small shops outside, it comes with warranty services, allowing you to return for repairs if any issues arise. Personally, I recommend prioritizing these brands when choosing films, as driving safety comes first, and they prove more durable and hassle-free in the long run. Also, don't forget to ask about the warranty period of the film, usually ranging from one to three years, to avoid future worries.
