Hi Roger,  You can do the same thing with liquid hide glue, especially
if the leaks are larger.  Use vacuum or pressure or a stiff pipe
cleaner to force the glue into any voids.  A vacuum cleaner has plenty
of pressure/vacuum.  I'd run a pipe cleaner into each hole to be sure
the channel is open before it dries.

Cleanup is easy: warm water on a sponge will wipe off any stray glue.

Keep in mind that the wood isn't really happy if you leave it wet for
very long.  But the tracker bar is pretty hard (like maple) so it won't
soak up much water.

P.S.: The tracker bar parts were originally glued together with hide
glue, so this is a fully compatible solution.  If you can apply clamps
while it dries, even better.
