Is It Necessary to Sun-Dry the Car After Window Tinting?
2 Answers
It is advisable to sun-dry the car after window tinting. Here are the reasons: Resolving residual moisture: Natural evaporation or drying in the shade cannot effectively address the issue of residual moisture, which may later lead to bubbles. Therefore, allowing the film to dry properly for a few days after application is a good practice. Normally, the moisture vapor between the film and the glass will evaporate in about a week. Wet application method: During the installation process, a wet application method is used. To ensure better adhesion between the film and the glass, although squeegee tools are used to remove moisture during installation, only about 70% to 80% of the moisture can be eliminated.
Right after I got my car tinted, I was really curious about whether it needed to be sun-dried. Actually, it's not absolutely necessary, but exposing it to sunlight can speed up the adhesive curing process, making the film stick better. When I had my car tinted last time, the technician advised me to park the car in the sun for two or three days, as this could reduce issues like bubbles or film shifting. If you don't expose it to sunlight, the adhesive will still cure naturally, but it might take an extra week or so. I remember during that time, I happened to be on a business trip and parked in the shade, which caused the edges of the film to lift slightly. I had to get it fixed later, which was quite a hassle. My advice is to avoid rolling down the windows or washing the car immediately after tinting—wait a few days to ensure it's completely dry. Also, if the weather is cold or rainy, you can carefully use a heat gun to warm the film surface, but don’t hold it too close to avoid damaging the film. In short, sun-drying isn’t a strict requirement, but it can save time and hassle, especially in summer when the results are great.
