You know those big 2 gallon garden sprayers with the pump on the can and the long hose with a sprayer on it, that's what I use.
I use it soley for Q, and mix up a gallon or so at a time. Pump provides plenty of pressure so when I'm doing turkey I will fill the jug with maple syrup and even that never stops it up.
Hell, I'll throw chunky barbecue sauce in there and use it instead of a mop.
downside is I got about 2 inches of sprayed crap all over the walls of my Bandera. first few smells of any Q is usually that of burning ants.
