AMEN!

What I do with tubing is use a piece of steel wool to bring it bright, taking off the oxidation. Then spray it thouroughly with a couple of coats of polyurathane varnish. This essentially making a big piece of magnet wire out of it. The only thing it supposed to help is with the skin effect. How much, I cant really say as I've never seen a difference between using either oxided or bright. On a rotary coil, the coil needs to be clean where it makes contact with the roller so I could see plating it. I have also seen some coils plated with tin. They worked just as good as any silver plate I've seen. They were plated using the electroless powder for PC boards.
