I know the frustration with Createx, especially when it’s your first paint system. It can seem an uphill battle getting it dialled in, but that is the challenge and all you want to do is to learn how to airbrush, not fight with your paint .....
Early in my journey I bought Etac EFX - wow ! Night and day!
Once I used the ETAC my confidence grew, my experience grew and my painting technique improved. once I knew how the a rush was supposed to perform, using the createx became easier as I knew what consistency and PSI I needed. Don’t give up until the Createx, but a couple of small bottles of primary ETAC and play away - cleaning up after Etac is a breeze
from memory PS is aimed more at hard surface applications and EFX at art surfaces
