Straightening and painting work with a body requires experience and knowledge of materials and processing methods. This is usually achieved only over many years of practice. Therefore, only the elimination of minor defects in the body and its paintwork is described here. For tinting, it is imperative to have paint of exactly the same color, since differences in color immediately catch the eye after work is completed. The paint color of the car is marked by the manufacturer with the paint number on the nameplate with the car code, located on the inside of the hood of the engine compartment in front. The paint number is on nameplate, located on the inside of the engine compartment hood. If there is a difference in color between the original and the repair paint, the reason is that the car's paintwork has changed its color over time under the influence of ultraviolet sunlight, extreme temperature fluctuations, weather conditions and chemical aggression, such as industrial gases. In addition, damage to surfaces and fading of paint can also occur when washing or caring for the paintwork with unsuitable products.
The Metallic finish consists of two coats, a Metallic primer coat and a clear lacquer finish. When painting, a colorless varnish is applied to the still wet ground. The risk of color differences is especially high when painting with Metallic, since here already different viscosities of the original and repair paint lead to a difference in color.
