If it is 10-100 ohms from the wall paint to the outlet ground, then
there is a ground path already. I expected it to be Mohm or too high
to register. Check with an AM radio, especially around the edges.
If there is buzzing, you want to find that ground and disconnect it.
Conceivably you may find it by noting where the radio buzzes more,
or with a very sensitive gauss-meter or buzz stick. It may be easier
to find after you connect your ground rod, as there could be a more
obvious current. 10 ohms is a decent ground, but not ideal for safety,
and if have buzzing it may make a big difference to switch to the
ground rod. But if not, adding a second ground rod could make the
buzzing worse, so if you can't find the first ground, you may be better
without the second. But just make sure nothing ever electrifies the wall.

To whoever asked:
The paint will reflect microwaves but is supposed to absorb as much
as it reflects. So in most cases you come out ahead, and if put
in the right place, can be a huge improvement.
