Gflex 655-1 Gflex pump rubber mounts bonding
I used the glue to glue the rubber mounts of a submersible pump, as the previous quick-drying glue of a different brand had loosened within a short time. The glue has been working perfectly for about two months.

Excellent product
While a bit on the expensive side this product is excellent for repairing your old cracked plastic water tanks.
And when I say expensive you also must take into consideration that you must apply generously for peace of mind ;)
In my opinion this kit is suitable for repairing a crack of 30cm which could be more than enough for some people.
