Check through the documentation for paint codes. The code for our Landau is on the build sheet glued inside a closet door. With that code, I was able to search online and determine that certain year Chrysler vehicles used that color. With that information, there are online sources for custom mixed brush and spray touch-up paint. I used
AutomotiveTouchup.com and was very pleased with the service and color match. Local body shop paint suppliers usually can also custom mix paints by paint code, but may not be willing to do small touch-up quantities.
