Metallic & pearl colored paints use flakes of aluminum metal, mica (a shiny mineral) or "pearl" (iridescent particles often from ground sea shells) to create sparkle, luminosity and more light and color complexity than is found in solid colored paints.
Metallic and pearl colors are available in
single-stage,
2-stage &
3-stage paint process technologies but they are not created equal.
The process and materials used in
2-stage paints result in a more uniform layer of color that causes the flakes to lie more flat, reflect more light and create beautiful finishes. The
single-stage process is not capable of achieving the same results and certain colors--especially golds, silvers, champagnes and bronzes--can look dull and grey in single-stage when compared to 2-stage and 3-stage paints. When color is important, choose 2-stage paint to achieve the right hue & brilliance.
For certain colors and special effects in finishes like "candies" and pearls--especially pearl white--it may be necessary to go another step into
3-stage paint to achieve the desired result. The Nissan Altima in the photo has a 3-stage pearl white paint job that gives the white a luminosity and brilliance that single- and two-stage paints cannot come close to.
