Gold FTW ! (when soldering)
I used to work for a company where long life and corrosion resistance were very, very important so almost all the electrical bits ended up being gold plated to some degree or other. For similar reasons, connectors were not allowed - everything had to be soldered. I have to say soldering a gold plated wire onto a gold plated pin was always a real pleasure - it's about the only time even a non-expert can get the textbook solder fillet!
