Snowplow drivers spray their blades with some "brew" of diesel fuel

Many
years ago my dad managed a rental yard, and one thing they had were trailers
that you could get filled with freshly mixed concrete.  They would spray them
with oil, perhaps just for rust prevention, but perhaps also to help the
concrete slide out.  The trailers had a jack that would lift the bed to dump
into a wheelbarrow.  Very handy for jobs that needed less than a full cement
mixer.
