Did Factory Undercoat the Fuel Tanks?

On the assembly line the drivetrain was installed as a unit from underneath of course. the shocks were dangling waiting for the rear end.

notice the wheel wells have undercoating all in them. The headpipes are installed. But can’t tell if tailpipes are on body or drivetrain fixture.

this is a Air Conditioning car so they typically get full undercoating.
