It takes about three to five days for the bubbles to disappear after applying the film. Here's how to apply car film: Clean the glass and spray installation liquid: Thoroughly clean each piece of glass, spray a small amount of window film installation liquid on the outer surface of the glass, cover it with the window film, and trim the film along the edges. Use a heat gun to shape and shrink the film: Use a portable heat gun to precisely shape and shrink the window film. After heat shaping, clean the inner surface of the glass with a strong liquid cleaner and scrub off the oil with a nylon soft pad. Apply the window film: Remove the protective film, spray installation liquid on the adhesive surface of the window film and the inner surface of the glass, and then apply the film to the glass. After positioning, remove the installation liquid: After sliding into position, spray installation liquid again and use a special squeegee tool to remove the liquid.

I also encountered bubbles after applying the film. At first, they were quite an eyesore, but the technician said small bubbles would disappear on their own within a few days as the moisture inside evaporates. If the bubbles are as small as a grain of rice, they dry faster in high temperatures and usually vanish within three to four days. However, if the bubbles are large or located in the center of your field of vision, it might be due to improper installation with too much trapped air, and waiting a week might not solve the issue. In such cases, avoid squeezing them yourself to prevent damaging the film—it's best to return to the shop for a free fix. Before applying the film, ensuring the technician uses tools to smooth out water and air is crucial. Opting for reputable brands with better self-healing properties can also help. Remember, high-quality films protect against UV rays and enhance privacy—never compromise on safety.

Last time I applied window film myself, there were a few small bubbles in the first few days. I asked an experienced friend about it, and he said not to rush to fix it—ordinary moisture bubbles might evaporate in about a week, but temperature, humidity, and film material have a big impact. In warm weather, it dries faster, while in cold weather, it’s slower. If the film wasn’t scraped clean during application or the film quality was poor, the bubbles might grow or even leave marks. I waited five days, and a few small bubbles disappeared, but the larger ones didn’t budge. In the end, I went to a professional shop to have it reinstalled. It’s recommended not to wash the car or touch the windows forcefully within 24 hours after applying the film—just observe the changes. When it comes to window tinting, it’s better to be safe than sorry. It protects against sun damage and aging, so don’t skimp on the necessary costs.

Bubbles are often caused by residual moisture, and small ones may evaporate and disappear within a few days. Don't rush to pop them; leaving the windows open on hot days speeds up drying. If bubbles persist or grow after a week, trapped air may be the issue, requiring rework. Ensure the surface is clean and apply adhesive evenly to minimize bubbles. Beginners often make this mistake—watch tutorials before applying the film.
