## Questions & Answers

**Q: After you applied this product to a pipe thread and placed the nut, do you have to wait, or can you start running the water right away?**
A: Depends on how much pressure there is. I know if you put it on a airhose fitting and then pressurize it right away, it won't hold and start to push it out of the threads. I think it takes 24hrs to setup fully.

**Q: Use on drinking water systems?**
A: Not sure, I used it on air lines outside. I would use Teflon tape on water.

**Q: Can one use teflon tape, then apply this product on top of the tape (for water pipe threads)?**
A: You would use one or the other, you wouldn't use both... this would take the place of teflon tape.

**Q: Can this be used on a high pressured air mattress hose?  I need something to seal the threads, but not close off the intake/outtake capacity of hose.**
A: Yes, you should be able to use it on air mattress hose, as long as they're threaded and not just push-on type connections

One bottle spilled in box and made a huge mess and it got all over the other bottles and it is going to be a lot of work to clean these up so I can use the other bottles
