I agree 100% BUT they titled the article "Tinned Wire Myth Busted" and then directed the answer more generally than to HIS particular situation.

The jacket of my wire was NEVER EVER submerged and that area is BONE dry except for oxygen and humidity. The bare copper oxidized because the JACKET or INSULATION failed to protect the bare copper from oxygen and humidity or moisture. This wire did NOT oxidize from bare exposed ends as this was a very tightly taped twisted wire & soldered connection (poorly and dangerously executed and why it failed to begin with). The wire under the electrical tape, at the ends, actually looked better than the wire under jacket.

I believe that! The factory wiring, not the DIY, on my CS is bare copper duplex jacketed and is also nice clean pink copper. The jacket on this factory wiring, was, and is a top quality bare copper though some of it, where the gauge was correct, now has heat shrink connectors.

Again, I agree "GOOD JACKED WIRE" will be fine this however is NOT what PS stated they applied this "good jacked theory" to ALL bare copper wire which is why I have issue because as I stated all wire is not equal quality and they lead the reader to believe otherwise..
