## Questions & Answers

**Q: Will it fix the tear in my fleshlight?**
A: No. It will not bond TPE> It is for silicone only.

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

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

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