Shielding Paint Mixup?

Shielding Paint Mixup?
Posted this to my timeline instead of here.. woops
I got to shielding a guitar of mine that has a laser etched piece of plywood for a pickguard (it looks really cool – I didn’t do it/design it, it came that way; pics can be added soon). I did the cavity with shielding tape but alas it did not stick to the plywood. This may have also been because I oiled it with Howard Feed-n-wax but jury is out.
So I got StewMac’s conductive paint and I did notice it was “goopy” at the bottom, presumably the metal in the pain to make it conductive. Can said to stir and I did the best I could but felt that I did not get like 80% of the stuff off the bottom/in suspension.
I did my 3 coats over 3 days and sure enough – no connectivity across the paint.
Anyone know of what I could/should do better to get that stuff mixed up right?

Andrew,
As you have guessed you need to break up that settled particles and get them back into supension. If stirring an/or shaking in the can won’t do it, I would try pouring it into a container that would allow you to break up the clumps with some sort of implement.

Ended up just using some chopsticks… Still had a couple tiny lumps but pretty sure it worked a lot better than before when I was just using a weak brush 😅
We will know when it dries I guess!

Oil finishing the guard definitely prevents the shielding paint from sticking. That’s really one of the advantages of using this type of finish on a guitar or furniture, it prevents dirt from sticking in the first place, kinda like oiling a skillet to prevent sticking.
Yes you do want to try to break up the solids in the jar of shielding paint. I use wooden coffee stirs to stir and break up chunks, works like a champ. Fortunately though, blotchy, uneven, and non-competely mixed paint still works about as well. You’re just using it to block unwanted electrical noise, so good conductivity is not essential.
