There is a crack in the glass bottle. How to prevent water leakage?

Spraying method: this method is similar to car paint touch-up, and the raw materials used are similar. Priming with putty, drying, grinding, spraying primer, drying, grinding and spraying topcoat. The advantage of this repair method is low cost, and if sprayed well, the repaired place is not easy to be found. The disadvantage is that it is easy to make the repaired parts yellow, discolored and peeling after a long time.

Glue gluing method: dry the inside and outside of the glass bottle thoroughly first, then wipe off the cracks on the bottle body, and then apply acidic transparent structural glue on the cracks (it doesn't need to be too thick, so as not to affect the stability of the bottle body, and it's best to make it as wide as possible). If it is convenient, it is best to apply the same glue to the mosquitoes in the bottle. In short: whether the bottle is transparent or not will not affect the beauty of the bottle, and it can seal the leakage well.
