Saturn automobiles are finished with a basecoat/clearcoat paint system. This process consists of an immersion primer on all steel and space frame components, a spray-on primer on all composite panels, and a high solid waterborne basecoat and catalyzed urethane clearcoat.

Basecoat/clearcoat finishes offer opportunities to readily blend and match colors. This blending is achieved in the basecoat stage. Providing the repair does not extend to the edge of the panel, blending of adjacent panels is not required to achieve a match. Due to Saturn's unique body construction and the absence of a sail panel joining the roof and quarter, it will not be necessary to blend in the top coat. All clearcoating can be accomplished on a panel-by-panel basis depending on the repair.
