I spray P60G2 but use a gravity feed HVLP. Can't help much with a high pressure siphon gun.
I can offer a couple tips. Wear a good respirator at all times.
1. Take the primer to a paint store and have them shake the bejeesus out of it.
2. Before mixing, stir the bejeesus out of it. Solids settle to the bottom.
3. Mix 1:2, paint:catalyst.
4. Spray only till you perceive and color change then stop. Usually two sets of passes at 90 degrees.
Start with the gun recommendations for pressure and paint valve. Pressure is at the gun with trigger pulled to the first stage (no paint).
Post your results. Someone here can help fine tune.
