Another way to get your copper bars nice and shiny is go to your local electroplaters and get a liter bottle of silver plating solution from their bulk tank, rub it on the cleaned copper with a rag, leaves a nice shiny silver coating without any electricity, so simple displacement reaction; the layer is extremely thin, but stops the copper corroding. Would not be as robust as tin-solder dipped. I used to do this over 40 years ago when making custom copper parts to fit inside high power RF transmitters. Cheers Mike
