Embarrassing admission....Happy Number 38 guitar to me.

Hi Ozzbike,
the 2.9 k ohm resistance sounds reasonable(!) for a thin layer. But I'm not sure what you should be expecting!
A 10 cm pencil line drawn onto paper typically has a resistance of somewhere between 10 k ohm to 100 k ohm - the variation depends on the type of pencil (or type of wax or binding agent holding the graphite lead together). At least you got less than that.

What was the resistance of the 3 coats?
Does the graphite powder conduct without the paint? Does the wet paint (with graphite) conduct?
Also, how are you measuring the connectivity?

Trevor,

Not much action I am afraid with this stuff.

I have read a couple of other things on the internet...and watched this fellows video.

I have added lots of graphite to the mix...little water each time. I have stirred and shaken with each addition and before each coat.

I am using the digital multi-meter pictured.

The top black line on the second pic has scratches from the red and black probes....not missing coverage. The bottom one has about four coats of varying ratio of graphite to paint to water.

I am now getting some continuity giving digital number readings when the probes are about 30mm apart now. I still don't get a consistent steady reading on resistance.

I will keep making tests and adding graphite until I either run out or get continuity and a steady measurement resistance.
