Overview - Vehicle manufacturers select colors, years before the actual vehicles are painted at the factory. Once these model year colors are selected, they are provided to paint manufacturers. PPG creates formulas to match these standards. There are many steps to the manufacturing process and variations can occur throughout. They may be due to one step being out of tolerance or a culmination of many steps being close to unacceptable. Examples of these potential variations include different paint manufacturers supplying the OE plant, different application equipment used at the factory, shearing of metallics as they tumble through the supply line, parts painted separate from the vehicle body, to name a few. The end result is that the actual car color does not match the OE standard. 1 TINTING: When the actual vehicle color does not match the OE standard and is not close enough to blend, the paint formula needs to be adjusted to get the color closer. This process, commonly referred to as tinting, is one of the most difficult tasks a paint technician performs during the repair. When tinting colors, there are five areas that the painter must balance: hue/color, value/lightness, chroma/richness, metallic size, and flop/angle perspective. It is a time-consuming process and rarely results in an exact match due to the variables described above. Therefore, PPG recommends tinting only to get the color to a blendable match. 2 SPOT REPAIR: When performing a spot repair, the idea is to minimize the repair area. The repair area receives full coverage and the surrounding area receives partial coverage creating an undetectable color transition. The entire repaired panel is clearcoated. If there is not enough room between the repair area and the adjacent panel(s), the color must be blended onto the adjacent panel. All panels that are painted should be clearcoated in their entirety. 3 FULL PANEL: When replacing a panel, blending color onto the adjacent panel(s) is a necessary operation that results in an undetectable color transition. If a spot repair occurs close to a panel edge, the color should be blended onto the adjacent panel(s) as well. All panels that are painted should be clearcoated in their entirety.
