## Questions & Answers

**Q: Is this product on wires (that have not been compromised) where the outside plastic coating has been damaged, like a computer power cable?**
A: Would work well to repair wire coatings that have been compromised.  May require multiple applications to build up the desired thickness allowing dry time between applications.  Works great!

**Q: If I used a different brush than supplied to apply this, what would I use to clean off the brush?  Thank you for your time and assistance.**
A: I am not aware of anything that would clean the brush. This is not paint. I would get an inexpensive throw-away brush and be done with it.

**Q: Is this product UL listed?  Thanks.**
A: But here is info from the manufacture that says UL will not approve due to various applications - same as what CV says...   https://gardnerbenderfaq.wordpress.com/2014/05/30/is-liquid-tape-ul-approved/

**Q: I need to drill a hole in the back of my car to run a wire through, behind the license plate. Will this prevent the elements from getting inside the car?**
A: You want to use a cable grommet, if you buy one thats already has a hole make sure it just a little smaller than the wire/cable you are using so it gets a good seal. You can buy them that doesn't already have a hole, again make sure that when you put a hole in it that its a little smaller than the wire. Keep in mind you have a outer diameter that you will size correctly for the grommet to fit in, and an inner diameter for the size cable/ wire .
