I think he might have misspoken when suggesting using pliers to effect
an extra quarter-turn on a PL-259 after first getting it finger-tight.
The "quarter turn" idea most often refers to the trick of backing-off a
screw "a quarter turn" and then re-tightening in order to break up
corrosion. More than one restorer has brought vintage equipment to life
by doing nothing more than that.
A second problem with using pliers to scrunch a PL-259 is the risk of
permanently deforming the barrel making future removal difficult if not
impossible.
Plier-tightening has its place, but hardly more than the degree or two
to which you alluded.
Take care of that dandruff!

I must say that over many years and without any ill effect I've never
bought into this idea of Gorilering up a PL259 with pliers beyond
finger tight. A quarter of a turn is an unbelievable suggestion. I've
just tried it and a couple of degrees is the best I could do without
being brutal and even then I don't thing it would go any further.
Urban myth maybe?
Also, I've never had a failure after simply applying a generous wrap
of self amalgamating tape, nothing else, to waterproof coax
connectors. Our UV environment is pretty powerful, clear skies and
sunshine can turn the skin on my head into huge dandruff seven days
later after 30 minutes exposure.

Don't forget to tighten the connector 1/4 turn after "finger tight" with
a pair of pliers to make a real seal.
