At the Norwood, Ohio, assembly plant, the body was dipped in red-oxide primer and that was used as the basecoat seemingly through ’76. Beginning in ’77, Pontiac began applying a gray-colored primer or sealer atop the red oxide before the exterior finish was applied. It’s obvious from this angle that there wasn’t much paint coverage on the lower edge of the rocker panel. It’s a constant theme we see throughout the lower-body area of this particular car. We also see that the small metal clip, which retains the brake line to the body, shows a hint of its original orange finish beneath the rubberized undercoat that was applied by the selling dealer.
