Three industrial paint coatings were exposed in a salt fog chamber according to ASTM standards and tested by both Electrochemical Noise and Electrochemical Impedance Spectroscopy.

These paint coatings were: (a) epoxy type; (b) polyurethane type, and (c) water-based type. These systems were ranked according to electrochemical techniques, which were later compared to each other.
