I've applied 2 coats of this gold colored shielding paint in my pickup cavities and cant seem to get any connection when testing with a multimeter. Thoughts? Maybe I'm just not using very good stuff.

Its maybe 3 years old. Acheson Electrodag SP-008A is whats on the container. Dist. by. Dill Engineering Saginaw, MI.
The strangest thing is I can actually put the probes in the container and not get a connection. I thought water would conduct fairly easily.
Are you sure your meter is functioning properly?
It's a water-based shielding paint for EMI/RFI. According to the material datasheet it's good for one year.
However, for this application my guess is it's probably still good.
Regardless, since in essence its a can of water filled with metal particles, you should be able to measure conductivity through it.

Maybe ill switch out the battery or something but it seems to work when the probes are touched together as well as from the bass string through the bridge ground.
Well I replaced the battery and the .2 amp fuse and its still not working as it should. Might just put it all back together and hope for the best.
Pure water is not a conductor.
Water purity meters actually measure the continuity between two electrodes in order to determine how contaminated the water is. The more current that goes between the electrodes, the more contaminated the water is.
Did you mix it properly before use?
Ya I shook and stirred it before application. Kinda wondering if my multimeter just isn't working right, although I was able to check the old 9v battery I pulled out, it was reading around 3v. May just have to assemble and see what happens. If it doesn't work I'll just get some more shielding and start over.
is the meter set properly to check continuity ..?? can you touch a couple points on the bridge or control plate to see if the meter is working ..??

Make sure the paint is dry before you test it... it's not going to show continuity before it dries. At least that's how the shielding paint works at work.
Ya I've tried a few things at this point. Multimeter is working fine. Going to have to go with the solid copper shielding I think.
Yeah, as deapestend says, let the paint dry first. Also, try using ohm mode on the multimeter. On some multimeters the continuity checker needs fairly low resistance to register. The paint may have slightly higher resistance than the continuity check expects.
I needed a pretty thick layer for consistent measuring results. Maybe just put on a couple more.

Whatever paint you are using sucks. Stop using it and switch to MG Chemicals SuperShield. It is, by far, the best product out there.
