## Questions & Answers

**Q: Does this work on clothing**
A: We used it to secure Electric guitar pedals to a pedal board. I am sure you can use it on clothing but I am afraid it may be too thick and too rigid for that purpose.

**Q: Does the adhesive stick to wood very well?**
A: I purchased it to apply to our outside canopy.  Didn't work too good.  However, I've used it on wood and plastic and it's still holding.

**Q: Can i use this to attach a strobe light to my dji mini three pro drone?**
A: Hard to say. Depends on the weight of the strobe. I can say that this stuff has a lot more holding power than Velcro.

**Q: No se adhiere a plástico en interior carro**
A: Dual Lock should adhere to the plastic interior of a car. Do keep in mind that it will likely leave a residue or discoloration when removed from the interior of a car so be cautious where you place it.
