ABSTRACT:
End portions of first and second metal plates are overlapped with non-cured sealant interposed therebetween. Spot-welding is applied to the overlapped end portions to assure tight joining between the first and second metal plates. The joined metal plates are then coated with paint and put in an oven for not only drying the paint but also melting the sealant. During this drying process, the melted sealant flows into an entire clearance defined between the overlapped end portions of the first and second metal plates. The joined first and second metal plates are then cooled to solidify the sealant.
