grounding properties for galvanization g30/40
i need to have a part powder coated for appearance purposes but a portion of it has to be unfinished (non-powder coat) for grounding purposes. however, i do want to protect the material from rusting. if the material is galvanized g30/40 this shouldn't affect it's ground potential should it? my prototype shop has this question and i wanted to check with you guys/gals before answering the question.
regards (and thanks),
srg.
