A contractor hired by the Port of San Diego began work to give a fresh coat of paint to Banner Art at the corner of Imperial Beach Boulevard and Seacoast Drive.
The fire engine red work of art that spells "ART" when viewed at an angle was made by Las Vegas artist and firefighter John Banks.
Banner Art was brought to Imperial Beach by the Port in November 2006.
Since then bird droppings and rust have taken their toll.
R.W. Little Company will first sandblast the sculpture to remove old paint and rust and will then apply marine grade primer and red paint, which will restore the sculpture to its original condition, said John Gilmore with the Port of San Diego.
The restoration is expected to take two weeks or less, he said.
While work is being done, Banner Art will be surrounded by scaffolding and plastic to ensure removed materials do not become airborne.
The Port of San Diego has brought several works of art to IB, including at the corner of Palm Avenue and Seacoast Drive, in front of the Marina Vista Community Center and at the end of Dahila Avenue.
