How long do auto repair apprentices usually study?
Generally, if you go to a professional school, it will take about two or three months.

It usually takes about 3-5 hours to shoot a car. If the curvature of the car is relatively large, it will take about 6 hours, and the construction is more difficult.

If it is a car with heat insulation and explosion-proof membrane attached to the whole car, it takes about 2 hours for a new car and 3 hours for an old car (remove the old membrane). If it is to change the color film of the whole car or stick the invisible car clothes on the whole car, it will take about 1 day for cars and 1 day and a half for SUV/MPV models.

However, the film pasting is purely manual operation, and the construction time will have a great relationship with the proficiency of technicians. The film can also reduce the damage of ultraviolet rays to the objects and people in the car. Through physical reflection, the temperature inside the car can be reduced, and the use of automobile air conditioners can be reduced, thus reducing fuel consumption and saving some expenses.

Precautions for car film:

1. It is very simple to know whether the explosion-proof membrane you choose is attached to the car. Take a short sample first, and compare it after sticking the film, and you will know if it is your own explosion-proof film.

2. Before pasting the film, carefully check whether the car glass is damaged. If the owner sits in the car and observes whether the color is uniform, whether there are bubbles, whether there are foreign objects and whether the car film affects the line of sight from different angles.

3. After the car film is completed, try to avoid lifting the window within a few days. Generally speaking, the film pasted on the windows on both sides should not be removed within 24 hours in summer and 48-72 hours in winter, because the film that is not fully bonded can be easily removed from the windows and displaced, and you should try to avoid washing the car within three days to avoid wet water falling off the car film.

4. After pasting, it is normal if there is fog between pasting and glass. Naturally dry out and disappear within 2 ~ 3 weeks.

5, especially the defogging line of the rear window glass, try not to open the film after one week, because opening it too early will easily cause the film on the rear window glass to bubble. In the meantime, if there is moisture, you can wipe the surface of the film with a wet towel, sponge or soft cloth.
