        Local spraying coat colors such as can be adjusted to the right, will bring convenience to repair, but the actual operation is very difficult to paint color and old paint color matching was exactly the same, even the same ingredients after spraying paint will appear color, in order to reduce the color of old paint, the majority of car maintenance by lacquerer many years of practice, has accumulated rich experience, the local color of paint spray to reduce to a minimum. Commonly used methods of operation are:
        1, mouth fade method. When the paint color of the paint can not be adjusted to the same as the old paint film, the color of the local repair can be gradually filtered to be close to the color of the old paint film in the construction operation. That is, in the last layer of spraying, in the original has been diluted in the paint to add appropriate amount of the same kind of varnish, so that after treatment can ease the new and old paint color difference.
        2. Local injection method with double sticky tape. By using the changing parts of the body, such as the angle, the double tape technique is applied before spraying. First, cover the edges with the first tape and cover the paper. Stick the edges above the edges, then stick second strips of tape over the first tape. After partial rectification, the visual difference caused by the brightness of the two adjacent sides of the angle can be utilized, and the chromaticity difference between the old and the new paint can be slowed down. This method is better for silver base paint. It should be noted that when spraying two layers of tape, you should try to thin, dry film, tear off the tape after grinding and polishing, to avoid hard edges.
        3, the use of doors or body parts, boundaries, folding mouth for the boundaries of local injection. Before spraying, the damaged parts should be polished and painted with two primers, and the old paint films which need to be sprayed are sanded with 280#~400# water and sand paper, and then be scrubbed with solvent. Then, the whole part is sprayed. After partial injection, the gap between the components can be transferred into the nozzle.
