Step 4: Apply conductive coat

Now, apply the stencil circuit using Super Shield conductive spray-paint. You will need to apply 2-5 coats of spray-paint for best functionality. Use the multimeter to test for conductivity and resistance. The trace resistance should be less than 10 -20 Ohms per foot. To decrease the resistance, add more coats of paint.

Make sure you functionally test the circuit whenever you can.
