[TheForge] Unique (?) coating for steel and iron...

No, this is not correct.  Polyurethane, polyester, and polyethylene are
three different polymers, also known as plastics.  Their properties and
suitabilities for various uses differ.  A polyurethane spar varnish may
be an excellent coating for iron - I wouldn't know.

The plastic in polyurethane is polyester, both are polymers which are
used
in the manufacture of plastics just as polyethylene is.
Applying a polyurethane varnish  with a high solids content to an
object
would have about the same effect as coating it with polyethelyne glue
as you
were describing.
