Dell used to paint the inside of their computers with conductive paint, but that is most effective for electric field radiation (above 30KHz) to pass the FCC emission rules.
If your paint measures good, it doesn't mean it's doing anything useful. It might still make you feel good knowing that it's there.
I know for a fact that many many people over the years have made unsolicited comments on how quiet my guitars are compared to theirs in the same room. I am doing a bit more than just using the paint, so you can hold any opinion you wish from there, but the silly paint works for me and what I do seems to work.
I once met a guy that built a full Faraday cage into/around his electronics workshop. Maybe we could talk him into using it as a jam room after hours?
