Oops
Hi there,
How embarassing. In the draft I meant to say "or", and also meant to expound a moment on the differences between the two treatments. Either will do nicely for chainplates, though regular polishing is usually easier to come by. Electropolishing is very handy for odd-shaped objects, with crannies that are difficult to get at manually. It also passivates the surface, though this can also be done easily with various acid treatments.
Fair leads,
Brion Toss
