Is the primary the same number of turns it
was, originally? Adding more primary turns (lowering the volts per
turn) will help. Wrapping a thick band of copper around the core in
the direction the turns wrap (an eddy current shield) may help contain
the stray fields a bit, also, at the cost of more waste heat and less
efficient heat removal.

These are your only 2 reasonable solutions.

Adding more turns to the primary -- will just a few % more turns make a
difference? I don't want to loose too much voltage. Also, I hope it's not
too important to match the gauge of the added turns to the rest of the
primary, as I don't have that exact gauge solid wire.

My original shield/epoxy question remains.

The stray field will probably go down faster than the proportion of
windings added. Any wire as heavy or heavier can be used.

If you don't want to lose secondary voltage, you can just add the same
proportional number of secondary turns, too.
