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.
