painting very fine PE mesh

How about trying higher pressure, thinner paint, and quickly shooting it? If you're lighty misting it, I suspect that at a microscopic level, the paint drops are significantly drying by the time they get to the mesh and thus sort of build up. I'm thinking if you can lay down a light, wet coat of fairly thinned paint on the PE mesh, the solvent will evaporate away, leaving a nice thin layer of paint on the PE without clogging the mesh.

Thanks :)

also, you can spray it, then hit it with just air from your AB which should remove the clogging.
