copper/epoxy bottom and zincs

[imported_Conrad]

So I'm sitting around trying to figure out what effect a copper or copper/epoxy mix instead of conventional bottom paint would have on how many zincs one should use, but my brain won't work. It seems the copper doesn't need protection, but what would it do for stainless shafts and stray galvinized fasteners. Would you need more zinc area, or would the zincs just go away faster?

Um, I think the proper question is, "Chemist, where are you?". :D
All of this stuff skimming of my head, no wonder I'm going 'follicaly challenged'! :D
