text: An anti-graffiti coating is a coating that prevents graffiti paint from bonding to surfaces.
  Cleaning graffiti off buildings costs billions of dollars annually . Many cities have started anti-graffiti programs but vandalism is still a problem. Companies across the globe are attempting to develop coatings to prevent vandals from defacing public and private property. The coatings being developed can be the paint itself, or a clear coat added on top of existing paint or building facades. Depending on the substrate and the severity of graffiti, different coatings give different benefits and disadvantages.
