Why paint doesn't always match

The task of matching the paint color of truck accessories with the vehicle’s color is becoming increasingly complex. The properties of paints in the aftermarket can vary greatly from the properties of the paint on the OEM vehicle manufacturers. Understanding these differences is a complicated task. The Light Truck Accessory Alliance (LTAA), with the assistance of the vehicle paint manufacturers, (BASF, Dupont & PPG) present this information in an effort to create a better understanding between the consumer and the retailer of truck accessories by providing the reasons why an exact color match cannot be guaranteed.

· Truck manufacturers use three different paint suppliers.

· Paint technologies can differ at each plant on the same type of vehicle. For example, “waterborne basecoat’ or “high solids” paints are two different paint technologies that are often used to produce the same color and on the same model.

· Different application equipment, like “mini bells”, “robotics”, “electrostatic” and “conventional spray” all applies paint differently, changing metallic and color appearance.

· Fluid delivery and air pressure variations in OEM plants can greatly affect color match consistency.

· A change in the same batch can even occur because of “metal flake shearing” due to constant mixing.

· The variation of film builds on the same colors over different color primers can change the final color.

· Multiple substrates on the car can affect color match consistency.

· Temperature, humidity, differences in the line speed, and piping distances can all cause a variation in color SEMA / LTAA, the vehicle manufacturers and paint suppliers are constantly working together to supply information that will improve the color match process.

· Vehicle color designers work closely with paint suppliers to carefully select a specific (and) achievable palette of colors.

· The possibility of obtaining a better color match can improve when a paint supplier provides color swatches to the vehicle manufacturers and the aftermarket industry showing variations in vehicles color code.
