The Golden Gate bridge gets painted end to end every year to protect it from corrosion.
Painting the Golden Gate bridge takes a lot of work and it takes an estimated 10,000 gallons of paint each year to fully paint the Golden Gate Bridge end to end.
I believe they used to only paint the Golden Gate Bridge every 7 years but now have decided to paint it every year due to corrosion.
The paint color in stores that is similar to the Golden Gate Bridge color is the International Orange which would be the closest in store paint you can find that matches the color of the Golden Gate bridge however you can't buy the exact color mixture of the paint that is used for the Golden Gate Bridge.
