Ditzler chip code 2185 is what I am using on the white areas of my truck.I had my local Lesonal paint jobber convert the code to their urethane single stage.It is a Chevy truck color used in the early to late 1970's, mostly as the center color on 2 tone trucks.
I am painting my 57 blue with white roof & interior. I have painted the grille HERE This white has a slight blue tint in it so it looks great with the blue body color. It should look great with black too, but beauty is in the eye of the beholder.

The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself." - John Stuart Mill (1806 - 1873)
