Thanks... I'm honestly not sure what brand my spray guns are, but I can tell you that they will be replaced before I spray anything again. They are an older, cheap set that I've had for years. The 1.4 nozzle worked fine for the Epoxy, but my 1.7 was too small for the high-build I sprayed later. Had some wasted material and poor coverage due it getting plugged up.. (which sucked to clean out). I'll probably buy a cheap (Northern Tool) gun with a 2.5 tip for the future high-build primer work. For the spraying sealer and base/clear later, I'm looking at the options from Devilbis.
