Mike,
The model that I use is the SATA minijet 4400 B hvlp 1.4SR.
It is perfect for our stunt models and will handle dopes, epoxies, automotive base coats, catalyze polyurethanes (aka “automotive clear”) with excellent results.
I’ve used many different types of guns, painting everything from cars and motorcycles to even a fridge and a stove along with model airplanes of course. This gun is by far the best unit I have used.
Bruce Perry turned me on to this gun. I think it’s his favourite as well.
