Most of the body is welded using spot welding during mass production in order to achieve maximum strength and efficiency. Spot welding is also the preferred method for repairing body damage to ensure the same level of strength and durability as a mass production body. However, spot welding cannot be applied in every instance due to the way the parts are assembled or for other reasons, Use MAG (plug or butt welding) or MIG brazing (plug welding) as specified in the model specific body repair manual instead.
