Thanks y'all!
Fellow painters, if you haven't tried the wet palette technique, I highly recommend it. It adds a bit of time to "setup" but it's soooooo nice. http://www.fullborerminiatures.com/articles/wetpalette.html
I was lining some interceptors last night, one in blue-grey, one in red, and when I was done with the red, my blue-grey (one drop) still had not dried out. It makes the paint a lot easier to work with without thinning it too much. Then all you have to do is occasionally wet your brush to keep it from drying.
