I’m looking for thin copper for corrugating. I’ve heard “roofing
copper” works, but my local has-everything-hardware store doesn’t
have it. They sent me to a local “professional” lumber yard, and
they didn’t have it.
So at this point it seems easier to mail order it. Anyone know
where? We’re talking 30, 32 gauge.
