Let me introduce to you the steps of 3M tape to make a sealing strip and stick to the door, as follows:

1. Under normal circumstances, the width of 3M tape is about 25mm, and the width of the sealing strip is about 8mm, so the 3M tape should be evenly cut into 3 strips.

2. Glue the 3M to the back of the sealing strip, then cut out the rest, and glue it together, so that it can be glued 3 times.

3. Before sticking the 3M tape as a sealing strip, the door should be cleaned. First stick a sealing strip of the car door, tear off the protective paper of the 3M tape while sticking, try to align it as much as possible, and remember to press it with your hand after sticking it.

4. After pasting, check the effect. The 3M tape seal cannot be pulled off by hand. It can only be torn off by tearing it from one side to prove that it has been pasted. Traces left on the door.
