I've had some similar issues with Poly-S and the plastic bottled Badger
paints of a few years ago. I might have as much to do with how latex
paint dries as the the size of the paint particles. I once started the
search for a very fine mesh screen to filter out large particles from
any kind of paint but never did find anything other than panty hose. As
I recall it worked pretty well though.

It's true. You can verify it by taking some latex house paint,
thinning it, and trying to spray it through your airbrush. It will
sputter and clog.
