RE: Klass Kote paint issues
Anything less than equal parts of reducer to parts A & B is definitely too thick, in my opinion. I have increased the ratio of reducer even further than 1-1-1, and have been happier with how well it flows through my gun; but, it is far more challenging for me to attain a consistent flow-coat, and yet still avoid causing a run on any vertically-oriented part. As a compromise, if I am "off" slightly on my ratio, I do err on the side of being a tiny bit heavier in reducer. But aside from that,1-1-1 seems to givemethe most consistent results.
If your not happy with the results, I would definitely suggest experimenting & trying it a little thinner. Just do soin smaller batches, and on scrap (or a less critical "sport" project), until you find what ratio works best for you. I do use the cheaper Harbor Freight detail and HVLP guns. Perhaps the spray pattern/characteristics of your new gun will yield better results. Good luck, and I hope you'll tell us how it works out for you. (Maybe we'll find I need to invest in better equipment, too!)
