Thats funny. I just called Sherwin Williams this morning and they guy didn’t know what kind of graffiti remover they had lol. 
On another note, how would you guys go about pricing a job like this? The area to be cleaned is probably 20-30 feet long and around 8 feet high. Obviously I’ll charge the cost of material, but assuming it works and I’m able to clean everything, or at least greatly improve the situation, how do you price that? It’s not like it’s a lot of labor, but I do have to take my pressure washer to clean everything off, there is the possibility of requiring multiple coats, and additionally, at least according to @Sharpe, it could take a long time for dwelling.
I appreciate any tips!
