Why Can't Car Film Be Applied on Rainy Days?

Car film can be applied on rainy days. Here are some relevant introductions about film application: Precautions for film application: When applying film, it is essential to choose high-quality film and have it installed by professional technicians. Substandard film may fail to meet light transmittance requirements, which could affect the driver's visibility during nighttime driving. It is not recommended to apply film on the front windshield as it may obstruct the driver's view. When applying film to the side windows of the driver and front passenger seats, two sections should be cut out to ensure clear visibility of the side mirrors. After the film is applied, avoid rolling the windows up and down as it may cause the film to peel off. Service life of car film: Generally, car film can last for about three years. After removing the film, a significant amount of adhesive residue may remain on the windows. Before removing these residues, it is necessary to soften them for easier removal. Attempting to scrape off the adhesive without softening may leave scratches on the glass. After softening the adhesive with alcohol or essential balm, use a plastic scraper to remove it, avoiding hard metal tools that could damage the glass.
I learned my lesson the hard way when I applied car window film on a rainy day. The humid weather filled the air with moisture, making the adhesive practically useless. Not only did bubbles form on the surface after application, but the film started peeling off within days—wasting both time and money. In my opinion, sunny days are ideal because the dry air helps the adhesive bond firmly. Normally, window film not only protects the glass but also blocks UV rays, but poor conditions can ruin the whole effort. I recommend checking the weather forecast and waiting for a sunny day, or finding a garage to do the job indoors. After several DIY attempts, I realized how crucial this small detail is—now I even pay attention to timing when maintaining my car.
I often discuss window tinting in car enthusiast circles, and everyone reminds me to avoid rainy days. High humidity can trap moisture between the film and glass, weakening adhesion and causing post-application warping or marks. Rainwater may also carry dust, contaminating the surface and affecting aesthetics and heat insulation. As a DIY-loving car owner, I recommend thorough surface cleaning, but overcast days make it difficult. Temperature is also crucial, as low temperatures slow adhesive curing. In the long run, films applied in bad weather have shorter lifespans, leading to costly frequent replacements. To save money and hassle, choose a dry period or consult a professional shop.
