Galvanic action caused by dissimilar metal contact may best be prevented by
- applying a non-porous dielectric material between the surfaces.
- special precautions are not required if they are properly bonded.
- priming both the surfaces with a light coat of zinc chromate primer.
Explanation from PART66Online
Galvanic corrosion between dissimilar metals is best prevented by inserting a non-porous, non-conducting (dielectric) barrier between them, which interrupts the electrical path and keeps electrolyte out so no corrosion cell can form. Bonding actually connects the metals electrically, and primer alone is not a reliable insulating separation.

non-porous dielectric material between the surfaces will prevent dissimilar metal contant.. isn't it?
