Seems that the SBST livery paintwork isn't as long-lasting as
the old livery. Paint begins to peel off, esp the roof.
A couple of buses, incl a Volvo MK4 Duple Metsec on svc 165 (can't
see the rego), has a white rooftop. I guess with a white rooftop,
paint peeling is not that obvious.
but the orange/red rooftop still looks much nicer IMO.
