I am using a combination of water/meth since I speculated meth evaporates quicker (reducing chance of erosion) and because the meth helps out with the fueling a little bit. I could go full water or full meth if I needed I guess.

It is quite tricky to set up an air assisted nozzle. You really need minimum amount of pressure on the fluid and ample air pressure. If you have too much fluid pressure, the atomisation is not that good.

Look at the following pictures, the difference is very visible.
