Highly Polished wire????

I don't want to mention names, but discussed "polishing" as well as "coating" some time ago with a manufacturer. He feels that it is a valid point and suggested that I try it with some of the DIY stuff I was playing around with @ the time. Except for low budget applications they have all of their wire produced for them to spec and do not repackage standard wire/cable as far as I know. I am lazy and never tried it. Maybe he will pipe in if he sees this thread? I don't feel comfortable going into the details of our discussions as I suspect that much of the info supplied was a part of their manufacturing process (really weird stuff that I would have never dreamed of - and I do have odd ideas). I have also misplaced my notes and would probably get it all wrong from memory - so don't ask. Anyway, if I were to attempt "home brew" polishing I think that I would pack a soft pastry cone with Talc and then draw the wire through it while supplying gentle preasure to the outside of the cone (this is my own idea, I think). The trick would be to not distort the wire and a gentle process would be in order.
