Spray a thin surface 1mm with water repulsion product.
Cut the circuit in this surface
Put the surface in a conductive paint bucket
Let's dry, check the circuit and recover with a 0.1-0.5 mm surface on top.
If this work, it would allow to make very thin surface with sensitive circuit in it or resistance based circuit very quickly and easily for production project.
Ok, I had an idea I need to try.
