ISO: Liquid Dirt Spray

Hello, I'm looking for liquid dirt spray! I have found a few options online, but shipping takes too long and I need it by Saturday. I have used this before by borrowing from a SFX make up artist, but I can't seem to find anything in time. Looked at set shop, the compleat sculptor, and amazon, but nothing so far. Does anyone have a good place? Fueller's Earth only comes in powders and won't give me the desired look. I need to quickly make windows/plates/items dirty and then quickly wipe it off. Non-toxic. Any help is very appreciative!
