Sadly Watshot is correct, just spoken to the Bodycraft chap and said it will vary and best is to try and match as close as possible. Paint can fade etc over time...
The information he has given me was:
Sherwin Williams
2k base coat
Water base
Code Kh3
Prospector no - ending in 3670
0 shade - Which basically means dark.
I remember us looking at the Paint samples and trying to match best with the paint to my car.
Katy you could always get the paint blended in to the other panels but will obviously cost more.
