One thing he points out is not to tin a wire you'll use a crimp
connector on, nor should you solder a crimped connector. You shouldn't
do the second because it destroys the strain relief, and you shouldn't
do the first because the connection loosens over time. Very, very
interesting, because Tefzel wire is pre-tinned...

Apples and oranges. Tefzel and many other wires are pre-tinned,
covered with a thin hard coat of tin or similar metals. You are
confusing this with the completely different process of "tinning" with
solder. Different chemicals, different processes, different thickness,
etc. etc.
