Going at the model with 20 psi is probably an issue. You can have clogs developing in the nozzle as the paint dries from so much airflow. Try dialing it down to about 12-15 if you can. I think Iwata might have a separate dial for variable pressure control outside of what your compressor pushes out.

Thinking about the paint there are different standards that milling of paint is done at. Airbrush paint is meant to go through some pretty small space. Inks, on the other hand, seem to be even thinner and can give good coverage. I’m having good luck with a white ink base for zenithal highligh and then gloss coating to avoid reactivating it once I put down paint on it. For you, with such large models, keep at the white paint. Set your pressure lower, mix your paint and backflush as you have, then try you airbrush. If anything else goes wrong I’d say try a flow improver from Vallejo as it’ll thin the paint but not dry it out as quickly. Remember, atmospheric moisture plays a factor as well to drying time. What you’re doing is running paint through a cold hair dryer and the stuff might just need help staying wet.
