It was commonly applied to inline six-cylinder and V8 engines during the mid-20th century.

This particular application is significant to automotive restoration projects and collectors. Correctly matching the original factory color is crucial for maintaining the authenticity and value of classic vehicles. Furthermore, it provides a tangible link to the era in which these cars were produced, evoking a sense of nostalgia and reflecting the design trends of the time. The availability of accurate reproduction products allows enthusiasts to accurately replicate the original factory appearance.
