A question for you A-body paint experts...did the factory clear-coat the engine bay after painting with metallics, or just leave them with the color coat? The color in question is GA4, Winchester Gray metallic on a '72.
Chrysler used TSA (thermal set acrylic) single stage enamels up until the late 80's then experimented with various solvent based base /clear technologies until they got to the waterborne base / 2K urethane clear-coats of today.
