I'm sure guitar paint is expensive because of the small quantities.
Even that paint isn't exactly cheap! Interesting stuff though. It's
seems to be a sort of aquadag (colloid graphite in water used to paint
on CRT tubes etc.) where they have substituted an acrylic water-base
suspension for the water. Apparently it retains the conductivity after
drying. yeah, sounds like an answer.

Of course you could coat the walls with adhesive and use metal foil
to coat them. copper foil would be best because you can solder the
seams for electrical contact. Aluminum foil would be nearly free but
making good contact a bit more tricky. Perhaps conductive paint down
the seams!
