Thanks for all the replies! Some of them I will admit was a little over my head but I still appreciate the time you guys took to reply. I think I will cover it with either chrome monokote or ultracote and then use the power down method of ground checking with a friend watch to see if there is any interference. Again thanks for all the replies and if someone out there does a test about this subject please be sure and let us know how it turned out. George.
