Abstract
In making a peripheral joint between first and second metal panels such as, e.g., outer and inner panels of an automobile door by hemming the first panel after application of a rust preventive sealant, the sealant is used in a quantity in excess of just sufficiency for completely filling in gaps in the joint to ensure that the excess portion of the sealant is pressed out of the joint by the end of the hemming operation, and the press die member used in the hemming working is formed with a groove in its hemming surface such that the sealant pressed out of the joint is confined within a space defined by the groove and shaped in conformance with the shape of the groove so as to serve as an external seal which closely covers the edge of the hemmed marginal part of the first panel.
