## Questions & Answers

**Q: Would this be useful to pre-emptively reinforce the corners of a suitcase before letting airport baggage handling throw it around?**
A: It's not an appropriate application. This product is a wrap to repair a fracture. I doubt that you could secure it around a corner. Even if you were able to get it to adhere, it wouldn't be durable. It would also be unattractive.

**Q: Is the tape flexible when you apply it, or more stiff?**
A: Flexible like tape when applied.  Then it hardens

**Q: Can this be used to reinforce the inside of a rotocast resin helmet?**
A: Not sure about your application, but my guess is no.  Fiberweld is a water-activated fiberglass wrap/strip.  For your application, you might have better luck with using a sheet of fiberglass cloth to form into the helmet and then apply fiberglass resin to the cloth to make a reinforced shell.

**Q: can you patch a nonwater pipe  with a half wrap**
A: Not certain what you are describing as a half wrap. If you only use half of what is indicated, you will compromise the strength of the repair. If it is a very narrow pipe, you might be able to use less but there should be at least 3 "wraps" around the breach for stability and strength.
