20+ years ago when I renovated my house most of the paint work had an
undercoat very much like tar. It appeared to be rather sticky even when
left for many weeks. A lot of hard work got it most of it off and a
coat or two of aluminium primer has stopped any bleed coming through
white painted surfaces.
