Yes. We all know that if this happened, someone in management would decide that "if we can get away with it for one season, we can get away with it for ever." And prevent the job from ever being finished.Would it be so bad if they left it for the first year like this and re did the weathered effect next close season?
I reckon that's just an undercoat , maybe they have tested for stress in those areas or something and so they have painted over the bare metal.It looks like the supports are having minimal paint work done to them. You can see the additional 'rust' on them as its a lot shinier compared to the rest.
