    You usually need to buff it because calcium builds up on it. If your in the states eighteen wheelers gas tanks are usually made of aluminum and they pay good money to get them polished.

      That’s very surprising to me, I’d always assumed tankers were stainless steel. Do they have to have a lining inside?

        They would have to now days. I don’t t think they originally did. My understanding is the stainless steel ones rust quickly.
