I use a leather strop to polish my chain, or I have one of the servants do it if I am feeling generous.
They get such a sense of purpose from a job well done.
On a more ridiculous subject I am having trouble finding a shop that will chrome plate Magnesium, any metallurgists know why?

Chrome plate is done via electroplating chromic acids of various sorts. As magnesium in an alkaline metal, and reactive in air/moisture, you have all sorts of issues. You can try and dig through what I found here.
http://www.finishing.com/71/52.shtml but it all reads about like this.
"
Magnesium can be plated by either using the zincate route or by direct plating. The zincate path uses an alkaline cleaner, followed by a chromic acid dip and another dip in phosphoric acid and fluoride. This is followed by a fluoride loaded zincate bath and Rochelle copper to about 5µm. The magnesium is then plated in electroless nickel.
The direct plating path is an alkaline soak, followed by a dip in 150 g/l CrO3 with a proprietary additive. This is followed by another dip in 15% HF at 25 °C and direct electroless nickel. The direct electroless nickel is a mixture of NiCO3/HF/ citric acid/NH3HF/ sodium hypophosphite/ NH4OH at about 85 °C "
I'm thinking that process probably involves a LOT of messing around, man hours, cost, etc.
