Should You Sun-Dry or Shade-Dry After Film Application?
2 Answers
It is correct to appropriately sun-dry after applying car film. Whether it's a new or used car, sun exposure is necessary after film application. Normally, there will be residual moisture and subsequent bubbles that need to be removed. Here’s an introduction on whether to sun-dry or shade-dry after film application: 1. After applying the film, the car needs some time to dry out the residual moisture. Professional technicians can remove about 80% of the water during the application process, with the rest left to evaporate naturally. If you choose to shade-dry, bubbles may remain, which can interfere with driving visibility in the long run. 2. Sun exposure helps eliminate small bubbles more quickly. After sun exposure, check the results the next day. If there are still issues, remember to contact the service center for further assistance.
I recommend letting the film dry in the shade rather than in direct sunlight, as sun exposure can accelerate water evaporation and cause bubbles. I just had my film professionally installed, and the technician specifically instructed me to park the car in a shaded area for 3-7 days to allow the water between the film and the glass to dry naturally. Remember not to roll the windows up or down for the first few days after installation—my neighbor rolled down the window on the second day out of impatience, causing the edges to lift, and had to redo the whole process. Although drying in the shade takes longer, the film will adhere more smoothly and last longer. If you really need to use the car urgently, you can turn on the air conditioning but avoid blowing it directly onto the glass. Also, avoid using cleaning agents on the glass until the film has fully bonded after about a month, after which maintenance becomes much easier.
