Really?

Sorry, David, I've just had one of my infrequent looks at my
e-mail, and I see a comment, so I re-open this to answer -
outbound mail is currently TU.

To expand on my "Really?": they don't put lacquer on copper pipes
to keep them shiny - it would seriously interfere with soldering,
so tradesmen/DIYers around the country would go purple with rage!
