Tom -

A self etching primer is one that contains acid that will help to etch
the bare metal and promote adhesion.  It is only needed on bare steel or
other uncoated metal surfaces.  When a vehicle is produced at the
factory the bare metal parts are run through a "washer" which not only
cleans but puts on a phosphate coating which etches and promotes
adhesion of the primer and aids in corrosion prevention.  A self etching
primer is an attempt to duplicate this metal treatment for use by us
shade tree mechanics and garage painters. 
It is probably the best primer for use on bare metal first coat but will
not give you much film build or fill qualities because it is usually
applied in a thin film and should not be sanded after application in
most cases.
