The most important thing to pay attention to when changing the car membrane is to do a good job of cleaning. Under normal circumstances, high-quality films and adhesives are relatively thin and easy to clean. Bad film, the glue is thick, the color of the film will be in the glue, and cleaning is very troublesome. At this time, cleanliness is very important. Compared with the new car, the old car has more dust than the new car. In addition, chemicals such as glue will adhere to the glass. If the cleaning is not clean, the chemicals left on the glass when sticking the new film will easily react with the lubricant, and there will be spots on the film. \ x0d \ x0d \ There are seven points to pay attention to when pasting film: \x0d\ 1. After pasting the film on the front bumper, stop in the sun as much as possible during the day, which will make the film on the front bumper dry faster. It usually takes about half a month to dry completely, including the rear gear. \x0d\2。 Avoid lifting the window for three days after the car film is applied. Because there is still water between the window glass and the newly pasted film, it is easy to cause the edge of the film to fall off when lifting the window glass, which will seriously make the film unable to stick to the glass again. \x0d\3。 Don't wash the car for three days. Due to the high water pressure of professional car washing equipment, water easily penetrates from the edge of the window, which will cause high water content in the edge of the glass and film, and it is easy to cause the edge of the film of Wrigley car to fall off when the window is lifted three days later. \x0d\4。 Vehicles with skylights travel within three days, especially at high speed. Don't open the skylight. Because there will be convection in the air inside and outside the car after the skylight is opened, it is easy to cause the upper edge of the front baffle to fall off. \x0d\5。 If the edge of Wrigley's car film bubbles, it should be repaired at the construction site within 24 hours. If it exceeds the time, the rubber around the bubble has dried out, and the periphery of the car film can no longer move, which will definitely produce creases. \x0d\6。 It is forbidden to stick the super adhesive label directly on the film within one month after sticking the film, so as not to cause partial separation between the film and the glass. \x0d\7。 After sticking the Wrigley film in winter, it is recommended not to lift the window and wash the car for a week.
