Is the car film applied on the inside or outside of the car?

The car film is applied on the inside of the car glass. Applying it on the inner side protects it from wind and rain, slowing down the aging process and thus extending its lifespan. Additionally, the film won't be affected by external interference during use, avoiding scratches or damage. The adhesion will also be more secure, preventing peeling or lifting at the edges. The functions of car window film include: 1. Heat insulation and sun protection, blocking a significant amount of heat from infrared rays; 2. UV protection, reducing the aging of car interiors; 3. Safety and explosion-proofing, preventing injuries caused by accidental glass breakage; 4. Creating a private space, preserving privacy and safety; 5. Anti-glare, reducing accidents caused by glare.
I remember being confused about which side to apply the film during my first time. Car window tint must be applied on the interior side, and the reason is quite practical: if applied externally, opening the window on rainy days would ruin it, and high-pressure car wash jets could peel the film right off. My neighbor Lao Wang took a shortcut by applying it externally, and the film started peeling and tearing within two days. Interior application blocks 90% of UV rays, preventing your arms from getting scorched while driving in summer. Special care must be taken with rear window defroster wires during application—experienced installers use specialized squeegees to avoid damage, so beginners shouldn't mess around. Also, make sure the windshield film has over 70% light transmittance to stay compliant; poor visibility at night is just asking for trouble.
Car window film must be applied to the interior side! Putting it on the exterior is just burning money. Think about it - the outside faces daily exposure to wind, sun, and rain. Even the best film won't last three months. I've seen too many failed cases in my shop: bubbles are minor issues, but when the film delaminates during rainy days when you roll down windows, that's truly embarrassing. Professional installers always make templates on the exterior glass first, cut the film, then remove and reapply it to the interior side - this reverse application often confuses beginners. Important reminder: never use dark tint on windshields, especially dangerous during rainy nights when visibility is compromised. By the way, leaving triangular areas untinted on front windows isn't just for show - it's crucial for seeing mirrors clearly when reversing to save your life.
