It was prior to Rudy G (and not Rudybaga) that the MTA began installing
car washing machines that they could run the cars through and it would
strip the graffiti. They also came out with cars that are resistant to
the chemicals used in the removal process... the more easily to have
graffiti stripped from them. They also made it more difficult to get
into the yard, but this is not very effective. The most effective
deterent to repeated graffiti is quick removal., the next best is
proactive community relations -- like having a really kool mural painted
on your wall by an accomplished graffiti artist. As far as I know there
are no passive options, meaning, you put the coating on the wall & the
graffiti stops. You put the coating on the wall and you keep stripping
off the graffiti. The coating makes it easier to get the graffiti off.
There are sacrificial & non-sacrificial coatings. The sacrificial
coatings strip off with the graffiti in short order, the non-sacrificial
coatings take longer to strip off. With some of the coatings they say
you can use water & a pressure washer to remove the graffiti, some say
you need to use a particular solvent. The question always has to be what
the coatings are doing to the substrate and is it better or worse than
what the graffiti, and the clean/graffiti cycle are doing to the substrate.
