I'd suggest minimum two, preferably three layers, stretched as close
to 3:1 as you can.  60 psi is definitely high pressure in this
application.  The issue isn't the opening itself -- it's the water
wedging its way along beneath the tape, which itself isn't sticky.

If the sucker doesn't start unwinding in your hand, it should be
cured sufficiently for use, always assuming that you use enough of
it.  Off hand I can't think of a pressure application where I'd think
one layer was enough, even at fifty per cent overlap.  And winding
tension is a big part of success both in bonding and in resisting
pressure from within.  Each additional layer incrementally adds
pressure -- try winding several layers around your finger to get the idea.
