Better yet, try re-reading the post, it's Cliff Barker, not Baker. I have now found his site and his rail is STAINLESS STEEL, as I said a whole new ball game. Stainless or to give it it's correct term, rustless steel, will not corrode but will develop an acceptable patina. It could still be prone to a build up of dirt on the surface, just the same as brass or nickle silver. It's electrical conductivity is a little less than brass or n/s but probably not so you'd notice on the kind of lengths that we tend to use. I would suggest that if you find a cost saving, or other advantage, go for it.
