I have done 4 coats of the paint now.....still NO continuity. I have to have the probes about 20mm apart to get some sort of reading on the multi-meter. I get great continuity from each little square of copper foil to the next...with a wire soldered to each point....duhhh.
So having a huge roll of the copper tape with me I attacked the pickup routs and the control cavity. This guitar will have the Rebel 90's from Tonerider in it. They are humbucker sized P 90's, so I was expecting some serious noise. Well now we have the best of both worlds I suppose.
Four coats of shielding paint and then a layer of copper foil tape. The continuity lights up across the board....nice. The wire in each pickup rout is under the tape...and the bridge earth wire is in through a tiny pin prick hole.
Neck time. Up to wet sand at 800 grit on the back of the neck and headstock to try and hide the "Head Case" decal there. The front took 1200, 1500, and then 2000 to work....so even though I am using a satin finish now, I still think it will be that many times to hide the thicker sticky tape.
Edit:- I think I will keep the paint as I have some older builds, basses in particular, that could benefit from it. I think I will water it down a little and drop in heaps more graphite.
Edit Edit:- Will the chrome metal control plate benefit from tape on its underside? I was thinking of just running a thin strip of foil around the lip of the cavity with a little tape on top and connecting down into the cavity. I would think that the chrome metal would act as an RF inhibitor....maybe it is copper etc that has the special ability?????
