Good results can be had with rustoleum,, Yes as a cabinet maker I have been spraying with pricey HVLP equipment for over 20 years, so I do know the tricks,,, It can be a challenge for new guys but I agree with Tom. IMO The work and learning curve is worth the effort in the satisfaction that you have built a one of a kind model.
My recent Rattle can renovation,, with a little help from an airbrush set up,, to get a finer over spray line at the green over grey bottom, I sprayed the paint into a paper funnel, let it drip into the airbrush cup, then sprayed that to get a finer line. I've used that same technique with Lusercote because it sometimes sprays so crappy out of the can
