Since 1995 there’s been a team of 38 maintenance people who constantly touch up parts of the paintwork that are eroding, but they don’t actually systematically repaint the whole bridge. Many paints/vinyl coating were experimented with prior to 1990 to find a covering that would be able to protect the bridge from the elements (especially the salt water) but not damage the air. Currently acrylic paints are used on the bridge.
