Window tinting can be performed on rainy days, with the following precautions for car window tinting: Protect interior facilities before tinting: Before applying the film, first protect the interior facilities by covering the seats and dashboard with plastic covers. During the tinting process, avoid using lubricants that may cause the film to fade. Also, do not apply the film under direct sunlight, as this can lead to wrinkles and bubbles in the film, affecting the car's aesthetic appearance. Cleaning the glass thoroughly is a fundamental step for ensuring the quality of the film application. Generally, cleaning the glass involves three steps: inspecting the glass for damage, removing adhesive particles and sand; dusting and cleaning the glass (since water is used for dust removal and lubrication, be careful to prevent water from leaking into the car's audio or electronic control systems—this must be done three times); and a final cleaning before applying the film. When cleaning the rear windshield, take care not to damage the heating wires. Do not wash the car for three days after tinting: For the first three days after window tinting, avoid washing the car as it may cause the film to peel off. After the tinting is completed, do not roll down the side windows for 24 hours in summer and 48-72 hours in winter, as doing so may cause the film to shift. If bubbles are noticed, they should be addressed within 24 hours at a professional car detailing shop. Additionally, for one month after applying sun protection or heat insulation film, avoid using strong adhesive labels directly on the film, as this may cause the film to partially detach from the glass.

Applying window film on rainy days is generally not advisable, as the film requires a completely dry surface to adhere properly. Rainwater contains moisture that can interfere with the even distribution of adhesive on the glass, leading to bubble formation or peeling edges. In my experience, even light rain or humid conditions can allow moisture to seep into the gaps, exacerbating issues when temperatures rise later, potentially requiring rework. It's best to choose a sunny, dry day for the job, ensuring the glass is clean and moisture-free. Before applying the film, wipe the window thoroughly with a dry cloth to remove any dust or water marks. If you must proceed in the rain, try to do it in a garage, though results may still be compromised. Remember, the quality of the film application directly impacts driving safety—bubbles or peeling can obstruct vision and increase risks. In short, waiting for clear weather saves time and hassle, making it unnecessary to take the risk.

A few days ago, I tried applying window film on a rainy day, and it turned into a complete mess. Raindrops fell on the car windows, and after hastily wiping them, I started applying the film. However, the adhesive quickly became sticky and uneven, resulting in bubbles. The next day while driving, the film began to peel at the edges and almost got stuck in the window. Later, I spent a lot of time and effort getting it redone at a repair shop. The experience taught me that rain makes the surface slippery, preventing the adhesive from bonding properly, which affects both appearance and durability. Ideally, choose a sunny afternoon for the task, with a room temperature around 20°C being most suitable. Also, check the weather forecast to avoid high humidity conditions. Car film is important for privacy and sun protection, but improper handling on rainy days can significantly reduce its effectiveness. I recommend learning from this lesson—wait for clear weather before attempting the job to ensure it's done right the first time.

Applying window film on rainy days is indeed unreliable! Moisture can interfere with the adhesive bonding, causing bubbles or peeling, which is frustrating to see. In normal conditions, dryness and cleanliness are key. If it's drizzling, don't rush the process—wait at least half an hour after the rain stops or use warm air to dry the surface before applying. However, even then, residual moisture might still pose hidden risks. While window film helps reduce interior temperature and UV damage, attempting it on rainy days wastes both time and materials. Consider planning ahead by choosing a stretch of forecasted sunny days for the task. In practice, wiping the glass with a pure cotton cloth can help remove moisture. In short, avoiding the rainy season for window film application is wise—patience leads to smoother results.
