Good product
Good silicone for adhesion and sealing. You do have to be careful not to squeeze the tube to tightly to prevent tube from splitting. Durable and easy to use, a bit messy to clean up if gotten on other surfaces.

Works on water leaks
I was able to successfully fix a water leak in the plastic lining of my door so I can say that it does work as a sealant. You should use a good amount, but it does actually seal things pretty well.

Works as advertise
I had a need for an adhesive that would not lose it bonding strength after a certain period of time. This loctite adhesive is pretty good stuff. It's holding up well so far , no complaints here. I would recommend giving it a try.

would be fine for "rough" joints, sealing. But does not flow smoothly from tube like regular silicone and you can't make a smooth bead like you can with normal silicone. No good at all for finishing type work. Tried to caulk the edges of a glass mirror where they met a black metal frame - just globs up and smears.
