Hi,

I have installed new copper pipes between the basement ceiling joists. I
do not intend to drop a ceiling and cover up the joists.

Is there a good way of preventing the shiny copper pipes from fading?
How about spraying them with exterior poly? Would that hold up to the
heat of the hot pipes?

Thanks,

Aaron

You can always polish copper later with a salt/vinegar solution when
it becomes dull, if you have not applied a clear coat finish.
