If the zipper latch cloth is rotten, we can use a lighter to heat this place a little to re bond it together, then insert the latch upward from the bottom of the cloth and install it, and finally drop 502 into the middle of the connection between the zipper latch and the cloth.
Many of our clothes have zippers. Usually, there is a hard thing at the bottom of one side of the zipper, which is called a bolt. When you fasten the zipper, you must have this thing to insert it into the zipper head and fasten the zipper.
The latch on the zipper is usually fixed on a cloth covered with plastic. If the cloth is rotten, we can use a lighter to heat the place a little, so that the cloth can be bonded together again.
Then we can take out the zipper bolt, insert it upward from the bottom of the cloth and install it. Finally, prepare a 502 glue and drop it into the middle of the connection between the zipper bolt and the cloth.
