How would you minimize galvanic corrosion with this technique, if it were used for cars?

edit: to be specific, this technique would seem to require that you prevent galvanic corrosion through surface coatings, but that doesn't seem to me to be a lasting solution for consumer automotive applications. It would seem like adhesives would be a superior choice since they can insulate the different metals from one another, reducing the need for the surface coating to maintain integrity.
