The short form is that Stokes recommends diluting alkyd oils with a substance called Liquin before using them. I set up some Perry War of the Roses infantry, put down a white gesso basecoat, and set to work.
The Liquin dilutes the otherwise pasty oils up to a point where they resemble vaseline. If you dilute them only slightly they resemble acrylics and paint on in a familiar fashion. The main difference is that the oils don't dry as quickly and so you can't paint a layer, wait a minute, and then go back and add more color. If you do the first layer just gets pushed to one side. If you dilute the colors intensely they can be used as a wash of sorts, hardly as agile as Citadel washes or inks but still serving a similar purpose.
Overall I had a pretty positive experience. Acrylics are obviously faster in all ways- faster to mix, faster to paint, faster to clean. The oils are superior in the luster of their color. They really stand out across the table and for pretty armies they will do a terrific job. They also smell good, which is not Completely trivial.
I'm not going to use oils for dark ages or WW II figures. I could well imagine using them for Blood Bowl, War of Austrian Succession, or Successors. In the future I think I'm going to aim for more wash effects and less attempt at a solid and precise color. But overall, a nice experiment.
