## Questions & Answers

**Q: Can I use it to fix  a tiny leak at copper pipe connection ? Thanks**
A: No. This is for attaching two copper pipes together, and it will need to cure for a little while before it gets wet. It won't help with an existing leak. I would try plumbers' putty, and if that doesn't help with the leak, you may need to pull the pipes apart. It'll cost a little money, but a plumber will be a big help.

**Q: Has anyone tried using this on flared hvac fittings that are having a problem getting a good seal?**
A: No, not tried. But can only imagine it would work well. However, flared hvac fittings shouldn’t really need this as they use threats, ferrules, and viton seals, correct? Anyway, I would just do an experiment: spend 10 on a bottle, assemble a capped tube using said flared fittings, and pressurize (standard pancake-style or alike 1XX psi compressor for pneumatic tools etc). Report back if pressure holds (compared to the control - compressor alone is good) ;)

**Q: Can it be used for jewlery making**
A: Probably not. I don’t think it would hold up to constant movement. I think it was a solderless method of bonding copper tubing and elbows together without using a torch and solder.

**Q: I have a turntable that only works on one channel, thinking there's a bad connection internally.  Would this product work for this?**
A: I had the same problem but after readjusting the two screws that attach the cartridge to the headshell the problem is fixed so I figured out the problem was the needle was not fit in the vinyl correctly, if it leans on one side then it only works on the channel it leans on, hopes it helps

### ⭐⭐⭐⭐⭐ Review
*by N***O on 11 March 2021*

My 2008 Yukon had one read defog tab ripped off. I tried a product from a store specifically to 'glue' it on - no good - completely disappointed. I used this in with a piece of copper tape which I got on amazon. The copper tape is conductive on both sides - yes - including the sticky side. Clean the area on the window so there is no dirt. I used a 1.5" long piece of conductive copper tape and taped it over the area on the glass where the tab is supposed to go. Rub the tape firmly on the window. Then, I used this product to 'glue' the tab to the copper tape I put put on the window. Prepare the tab by sanding it so it is shiny copper. I poured a thin layer of the red liquid on the back of the tab and placed it in place on the copper tape. Apply good pressure for 2 whole minutes AND DON'T MOVE IT. It stuck. I let it be for 10 minutes and then gently and carefully placed the electrical connected on the tab. I turned on the rear defog switch and used a multi-meter to determine there was voltage on the window. There was..and it works. It's too bad that they don't sell a smaller bottle. I only used about 15 drops in total. Good luck to you.
