Could anyone give me some tips and advice on getting a really good, shiny, smooth finish on sterling silver discs (1mm thick), please. I'm using them for doing stamped jewellery. I get the discs from Cooksons but some have a very scratched, dimpled surface. I've used pro-polish pads until my hands and fingers are so sore I could weep!

Any advice or suggestions would be appreciated.

Thanks.
