The salon where I work has been graffiti-tagged several times over the past month, and while we have been cleaning/covering over the damage ourselves (after an initial, lengthy storeroom search for the old can of correct-color paint), I'm wondering if anyone has had success with the various graffiti removal companies whose vans I've noticed around town. Our tagging has thankfully been quite small in scale, but I'm curious to know what other options exist in case the problem becomes larger or more frequent in future. Any thoughts would be much appreciated!
