I agree.
Assembling and soldering a PL should'nt be done elswhere then in a workshop,
with adapted tools. A few hundreds one after an other in the ideal
conditions is OK.
It's a very critical operation if you dont want cold solder which break at
the first occasion, or burned joints which have a transfert resistance of a
few  M ohms
.........Soldering guns !!!!!!!! throw them away, you will be unable to
control the right temperature.
Use a N type, sure you will have better results for years.
By the way, nowadays one can find PL to be mounted as N-type. ( at least in
Germany ).
Have been in charge of ANGRC and other military production  for a couple of
years in the late fiftees.......
