I am re-finishing a 1956 cadillac sedan deville. its original colors were two-tone. Camelot Gray(paint code 18) was on the roof of the car and Dawn Gray (paint code 16) was on the body. I have a paint chip chart from 1956 and you can see that Camelot Gray is really a dark bluish color and Dawn Gray is a light lavender color. But the paint sores I have gone to can't seem to come up with the correct formula to mix up some. Has anyone had or done a repaint job using these colors, and if so where did you get the paint or who painted it for you.
