Will it fix the tear in my fleshlight?

No. It will not bond TPE> It is for silicone only.

how to save prolong Opened shelf life? Best way to store? Since its really expensive.

The best way to prolong the shelf life is to store at room temperature - 73F, 23C - in an air tight container, with the cap fully closed.

i have a flexible silicon tablet case... can one use this to stick a thin metel sheet to it ?

This is about the only thing that will bond to silicone, so yes. I'd use a fine grit on the metal first to provide a better bonding surface.

Can something be added to accelerate the cure? I heard a catalyst could be added but I don’t know which.

personally I never heard of this so I would contact "Smooth-Inc" themselves and ask them cuz know alot more. just make sure you tell them exactly what your doing with all the details.
