Way back in the day vehicles were manually spray painted in Detroit car factories. The excess paint would accumulate in layers and harden over time. Then they would be cleaned out and thrown away. But many people at the factories would collect the pieces of harden paint which looks like stones.
The paint which became fordite can be cut and polished. The paint colors are unique and the Detroit agate have become collectable precious memories of Motor City history.
