This may color your outlook: There is.

USC, the Natural History Museum, and much of L.A.’s public housing have been treated with a spray paint-resistant coating. Mural artists have used the polyurethane protectants like Amershield for years to stave off tagging. Beyond that, a call to 311 will generate a latex touch-up for your building should it acquire unwanted embellishment.
