## Questions & Answers

**Q: I'm using a gas soldering iron to solder thin alarm cable, i find the solder doesn't stick to the wire and keeps rolling off, will this product help?**
A: I found that corrosion of the wire is what causes solder not to stick.  Cleaning the copper with sandpaper until it is bright and shiney should fix it.  I also tried soaking the wire end in a solution of vinegar and salt for 10 minutes.  Then dunk the wire end in baking soda and water to neutralize the acid and stop further corrosion.  I did not find that the flux was the fix.

**Q: Somehow I thought I was ordering tinning paste, but landed up ordering this. Would this work for tinning tips?**
A: No it is acid based and I read on a document you should not use acid based paste. There is tinning pastes on sale for approx £5

**Q: Is this OK to use for soldering rc battery bullets?**
A: I know it's late but yes, you can use this for bullets, I've soldered bullet connectors with and without flux.  It will work fine

**Q: Is this suitable for silver solder for Flame soldering brass to brass?**
A: I have used it for soldering in model railway work with wiring and it helped. It was a recommended solder for model railway work.  We did try to solder some silver jewellery without success
