Here is what I am using. The formula for the Sherwin Williams powdercoat color is shown in the pictures. Any Sherwin Williams AUTOMOTIVE paint store should be able to mix it and put it into a spray can. The stone touch color is Gotham Grey. Larry Geiger tells me it is available both at Wal-Mart and the Micheal's craft stores. The can at Micheal's may be a bit different but it is the same color.
