Disclosed are methods for passivating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods comprise the steps of depositing an electropositive metal onto at least a portion of the substrate, followed immediately by electrophoretically depositing on the substrate a curable, electrodepositable coating composition. The present invention also relates to coated substrates produced by the above methods.
