I reiterate, if you don't want a catastrophic water pump failure,
replace the water pump.  No "leak stop" material, regardless of brand,
is going to reverse or stop the water pump damage that is causing the
leak there.  Internal parts are worn, and they will continue to wear
until suddenly the pump seizes.  When it does, all hell will break
loose.  If you remove the worn pump, and try to turn it by hand, you'll
find that it turns with difficulty compared to a new pump, likely with a
grinding feel when it turns.  Bearings, shaft, something is damaged.
The leak is only a sign of internal wear.
