Reverse Graffiti in South Africa

We’ve tossed around the idea of engaging in some form of reverse graffiti in Windsor for quite a while now. I assume there must be a few Windsor buildings dirty enough for a nice contrast-heavy design. Any suggestions? I think the Hiram Walker storage facilities near Russel Woods are covered with a black residue, but the premises are private and probably inaccessible. Apparently there are no laws prohibiting reverse graffiti in this part of South Africa. I wonder if we have any? I’d like to find out!
