I’m in the process of cleaning all my copper parts before assembly. After all that work I want to keep all the parts shiny. What have members used to keep their units shiny? I’m taking long term shiny I don’t want to be constantly cleaning it. Lacquer, varnish, polyurethane, and beeswax? I like the beeswax idea but I don’t think it will stand up to the heat.
