Way back in 2011 I used CUPro conductive paint to test different application methods for circuit boards and LEDs. Thanks to my impeccable filing system I just found the sample papers and the paint.

GOOD NEWS – the paint is still is working as a conductive trace! In fact even after three years the resistance remains the same.
