RG570 and shielding paint in control cavities
Hey, I have a 1991 RG570 that started buzzing recently and I found that the ground wire had come loose from the tremolo claw. I also opened up the control and jack cavities while I was there to see if everything looked ok. On a whim I decided to check the shielding paint that I found in those 2 cavities and it does not appear to be conductive at all according to the meter.
I'm not the original owner so I wanted to ask if these models did have shielding paint installed in them at the factory? Or did somebody just blow it and use the wrong kind of paint?
