I only used a HVLP gun with good results. I stll spray with the conventional JGA gun which I become accustomed to. I have been spraying paint for more than forty years. It took me almost that long to learn that when I thought I was finished spraying I then put down another coat. This my friends made and makes all the difference in the world. By doing this there is a big improvement in the finish and the gloss. By the time I have everything figured out I will no longer feel the need to spray paint. It's too bad I/we can't pass this experience down to the next generation. I suppose they to will need to learn they hard way. :>)
