just a simple domed men''s band - I would like to every once in a while - no more than say 2x per year - polish this band to reduce the effects of the light surface scratches it gathers - but I would prefer to not take to to a jeweler from a time perspective - I have been told only rouge polishing is needed - so - can I do this myself - is it a matter of buying some compound and tools - and being very careful - if so what to buy, where to buy and how to do it? Is it something I could totally screw up?
