The color first appeared on the 1957 Corvette and continued through 1959. Fender used the color from 1960 until 1965. The color has a high metallic content but due to the fineness of the metallics it is very easy to apply. Unlike some metallics If too wet of a coat is applied Inca Silver dries flat and consistent. The color can be used with or without a clear coat and a white primer is preferred.
