1. Clean the joint between the decorative strip and the body surface with a cotton cloth dipped in alcohol;

2. Dry the moisture on the car body and decorative strips with a baking gun;

3. Stick the decorative strip with 3M double-sided adhesive and bake it with a baking gun to maximize the viscosity of the double-sided adhesive;

4. Smooth the decorative strip and press it evenly, so that the decorative strip can be bonded firmly and stably.

When the door decorative strip is loose, inclined or dropped, the easiest way is to stir up the decorative strip and apply some glue. Because the decorative strip is loose and inclined, it will not only affect the appearance, but also affect the sealing (poor sealing will reduce the life of the glass lifter) and the sound of closing the door.
