Although the Good Ship Bougainville was less than a year old, rust was a constant problem, so a programme of painting was ongoing.
Every bit of rust was ruthlessly hunted down and treated with not one, not two but three coats of paint.
And there are an awful lot of nooks and crannies on a big, ocean-going ship.
And lots of places for rust to lurk.
Don’t ask. I have no idea!
All I know is that I’m glad it wasn’t me.
