EDIT: Also Pilot markers and http://www.amazon.com/Marsh-Black-T-Grade-Pigment-Quart/dp/B007V5507U/ref=sr_1_1?ie=UTF8&qid=1369244577&sr=8-1&keywords=marsh+ink
EDIT2: Don't put the pure Marsh ink in the sprayer. It's a waste. Also mix the Marsh T-Grade with Garvey to get it to stain. Example video: http://www.youtube.com/watch?v=y2IFU-f2mkc
