Here's a common problem for those of us who live in urban, population dense areas: Taggers keep getting the block walls in the neighborhood, of course using spray paint. Is there any product available that spray paint will wash off of that can be applied to the walls after painting them so repainting would not be a big issue after the taggers have toured through the area? -Molly
Molly, we've been the victims of vandalism and tagging also, and we've primarily contacted the city to cleanup the spray paint blight quickly with a simple call to (866) 4LA-CITY to call in the cleanup cavalry. You can also request cleanup quickly and easily online at the LA City Anti-Graffiti Request System.
But to get back to your original question: SEI Chemical of Northridge, CA offers a product called Graffiti Proofer Anti-Stick, which literally causes graffiti to run off protected surfaces, frustrating the vandals, and making clean-up in most cases as easy as washing a window:
"The GPA-200 is the world's first graffiti deterrent coating as many spray paints will simply run off, thus deterring the vandal from continuing. This coating is impervious to UV degradation and it is highly resistant to hydrocarbons, corrosion, graffiti and a wide variety of chemicals."
