## 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 .

### ⭐⭐⭐⭐⭐ Excellent for repairing wiring harnesses
*by Z***L on July 11, 2024*

When diagnosing electrical issues in cars, I prefer to use a piercing tool to poke through wiring insulation so I can connect a multimeter, test light, or oscilloscope. Some people say you should back-probe the connector and that poking insulation is for hacks, but I've run into plenty of instances when back-probing a connector "fixes" a corroded or intermittent connection. Good luck trying to fix the problem when you can't get it to act up. Piercing the insulation means that you have to seal the hole back up, and that's when liquid electrical tape comes in. A quick dab seals the hole in the insulation. Not too long ago I had to use this to repair an engine wiring harness. The insulation had split on several wires in the harness and the conductors were intermittently touching one another, setting all sorts of trouble codes when the signals shorted. I grabbed the liquid electrical tape because the alternative was to cut, solder, and heat-shrink about a dozen wires in a cramped engine compartment. Instead, I cleaned the wiring harness, dabbed liquid electrical tape over each bare conductor, let it dry, and used wire loom and cable ties to secure the harness and keep it from moving. It's been almost a year and I've had zero problems with the wiring harness. This stuff is a life-saver for quick repairs, especially in difficult-to-reach areas.
