good additive to mops. I got some stuff from my school called "waterproof black drawing ink" made by a company called chromacryl,(its an australian brand but you could probably get a similar product at art shops in the US). It is a similar consistency to honey, i have added it to my mop and to my posca and it makes a thick, opaque flat black (depending on the ratio used) definately a good find.
