Possible, but I don't think so.

More likely. Did you hone the inside of the m/c? Sometimes a few
slow turns with a hone to break the glaze on the inner surface of the
m/c is all it takes to get a good seal. And like you said above, it
only takes an hour. A low-budget hone will only cost you $5-10 at the
hardware store.
Coat the honing stones and the inside of the m/c with brake fluid
before you begin. Use a variable-speed drill, and make sure you
don't spin it too fast or too long in one place inside the m/c. Total
running time for the drill shouldn't be more than 5 seconds or so,
just enough to break the glaze and give the seal something to grab on
to. I have used this technique on my car's clutch master & slave
cylinder, and also brake m/c, with excellent results.
Best of luck,
