What is your nozzle size?
If nozzle is on the small side, open fluid control wide open.
I would start with fan wide open also.
Bring your pressure up till atomization is good.
If your spray pattern is uneven try to choke the fan just enough to achieve even pattern.
Using a test panel determine how fast you must move the gun.
Fast production speed is good to ensure wet on wet.
By the way, I have some expensive guns and some new cheap guns. I am amazed at how well the cheap guns atomize the paint. For me, it is easier to get good atomization with compliant/conventional guns than HVLP; maybe because that is what I am used to.

just bring the pressure up about 5 lbs at a time until you get the paint to lay down..

how should epoxy lay down?
I've been shooting a few parts with Omni MP172 black epoxy over the last few weeks and I'm not sure I'm getting the right results.
The paint covers relatively well, but it has a rough texture - tons of peel, I think. Not smooth at all.
I've tried it mixed per the tech sheet, and also reduced around 10% with acetone (also per the tech sheet), with no real change. It seems to be smoother in spots where I hesitated or accidentally got too close and the paint went on thicker.
I probably have the gun not setup right, and am not consistent enough with my technique, but I wanted to check before I go fiddling with settings.
Should epoxy lay down perfectly flat assuming everything is done right?
If it should be flat, any guesses on what adjustments I might make? I have a cheap Princess Auto HVLP (I think it's a HF 43430 basically), running about 25 psi with the trigger pulled, full fan, and 1.5-1.75 turns out on the fluid knob.
