Heres another idea - get a big rubbermaid tub, install a cheap large spigot. Attach the spigot with a piece of tubing which is attached to a large T of PVC pipe. Make it say two truck widths long! Drill a bunch of holes the length of the tube (Like something you see a farmer use to sprinkle liquids on his crops behind a tractor.)
Dump all the paint in the bin and add a bit of paint thinner to make it flow faster but not enough to dilute it too much. Deploy the pipe so it lays on the tailgate and open the valve! Boom, a 10 foot wide paint dripper! You can plan a route to stop at a dumpster and toss the whole thing when done, and you lose only $50 or so. And probably less mess potential. You can also test it out ahead of time with a coupe gallons of paint to make sure the flow is good.
Bonus: Drag a piece of plywood with a 10 foot rope and it will act like a big brush to smooth out the drippings into a solid mass for full coverage. Cut the rope and leave the plywood.
