发明名称 Vehicle coating process
摘要 A process of applying a finish to an electrically conductive vehicle body by passing the body through a water-based electrocoating bath while applying a voltage between the body and the bath to electro-coat the body with constituents of the bath. The coat is dehydrated to a state of sufficient dryness to permit spray application of a water-base primer while maintaining the coat cool enough to avoid fusing the coat. A coating of water-base primer is then sprayed over the dehydrated but otherwise untreated E coat. The coat and coating are then baked to concurrently fuse both of them. The primer sprayed on an interior portion of the body is pigmented to a desired finished color. Selected portions of the baked coating on the exterior of the body are light sanded to remove entrained dirt and thereafter finish coating is applied to the body.
