What does shielding tape do? Shielding tapes are products designed for applications that require point-to-point electrical contact, grounding, and static charge draining. These tapes contain signals produced by your device, as well as block outside signals that could affect internal components.
How do you shield a guitar with conductive paint?
Apply Electric Paint
With your guitar open, apply the conductive paint with a brush to the insides of the guitar, covering the guitar cavity and pickup cavity. Make sure to get an even application as well painting any of the connections within the guitar, this will improve the conductivity of the paint.
