[DML] Re: Frame Flex? (weight of galvanising)

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

Galvanizing (zinc coating) is an excellant way to preserve a mild
steel frame. The drawbacks include a weight penalty and possible
warpage. Even scratches are self-healing to an extent. The zinc
sacrifices itself to prevent the steel from oxidizing, just like the
zincs you would use on a boat. It is not commonly done on cars because
of the weight penalty and the expense. Instead the auto manufacturers
are moving over to composites and plastics. Look at the wheel well
housings on a modern car, they are plastic as are the fasteners. You
will see a composite frame in the near future just as JZD had
origionally plannned for the Delorean! Another drawback to zinc
coating is the danger of welding and grinding. You MUST protect
yourself against the fumes from welding and the zinc dust when
grinding. The dust and fumes are very toxic.
