The video very much needs some words to explain what you are doing an why? I can't tell exactly what the damage is that you are repairing. How would that speaker have gotten damaged that way? It looks like you are mixing some sort of two part glue, maybe epoxy? But, why is it in water bottles? And, why epoxy? Why does it turn white when mixed? Epoxy seems to me to be heavy and not flexible for this type of repair.
