Which side of the car film should be heated when shrinking?

[GageLynn]

There are two methods for film shrinking: dry shrinking and wet shrinking, which mainly depend on the technician's operating habits. However, regardless of the method used, uniform shrinkage must be achieved. This means that during the shrinking process, directional considerations should be taken into account first, with the midline as the reference point, and both sides should be heated symmetrically and evenly to achieve film shrinkage. Additional notes: Pay attention to the temperature, the distance from the film, and the local heating time during the shrinking process. For dry shrinking, it is best to use a wet cloth to draw a horizontal wet line in the middle of the windshield, then attach the film. After pre-cutting the edges, use the wet cloth to draw two vertical lines on the edges of the film to basically fix it and ensure uniform shrinkage.
