For generations, people said painting the Forth Bridge never ends. On 9 December 2011, it did. 🌉

The secret wasn't faster painters. The old paint was blasted off, and three new layers went on: a primer, a glass-flake epoxy from the offshore oil industry, and a top coat. Network Rail said the bridge wouldn't need a full repaint for at least 20 years.

Long life isn't luck. It's specified for the place the steel has to live.
