Electrocoat over Zinc-Plated Steel—Revisited
I wonder why you think the automotive community should be questioned for specifying a zinc or zinc alloy prior to E-coat. Performance testing done by all the major OEMs will confirm better corrosion performance with zinc or zinc alloy than with a phosphate base. I think you should revisit your response.
