Lead does not stay bright in air. When you took the paint off you took
the corrosion off with it.

Err. so there was air under the paint and thus corrosion, what is the
point
of paint then ? There was not corrosion because the paint had kept the
air
from the surface of the lead, as it's designed to do !...

Possibly, though we cant simply assume that option. Any case, the
earth bond can not be assumed to be gas tight.

No argument there, I was just questioning your reasoning behind the paint
remark.

I assumed decorative, do you think there is a different purpose?


Decorative is a secondary function, protection is the prime function, even
though it's not always used as such IYSWIM.
