Unless you are painting the entire coach you should have the body shop match the colors. If you give them the names and paint codes for the original paint they will produce a paint that will match your color as it was when manufactured 19 years ago, not as it is faded and aged today. Put the responsibility for matching the paint where it belongs, with the body shop.
