Factory Underside paint?

[crowe-t]

Does anyone know how the underside(of the floors) of the GMC Sierra trucks' cab and bed were painted from the factory? Were they factory body color misted over primer?

My 1980 was black on the bottom of the cab and bed... Original body paint was like a metallic charcoal grey with a blue stripe

Pretty sure it varied from year to year and plant to plant. There were different sealers/primers and most likely different amounts of body color overspray.
