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.
