Interesting article that shows electrically conductive paint in many potential uses…. My favorite is the light switch that is painted on the wall.
I could see this being used by electricians, audio/visual installers, ceiling fan installers etc who could use this product to paint electric connections directly to the wall, then simply paint the wall color on top of the circuits to hide them. They would not have to cut into the walls which creates a ton of work patching, texturing, and painting. Without all the wall repair, early adopters of this new technology might be able to provide more competitive bids while earning more profit and serving customers better.
