Quoted from Rum-Z:I actually like the Createx, so I'm not much help suggesting something new. However, I've had good luck spraying down a base coat of white, then overlaying with the yellow. That's a whole extra step, but one that has worked out for me. I'm just throwing that out there in case you don't get any other suggestions.
I do the same with the white. The I tersting thing is that. Have had white weep under the mask a few times so now I spray a thin color coat first and heat cure it and then spray my white coat. Then add the yellow layers. Haven't had a weeping issue since I did this. Could be a total coincidence but it has worked well so far. I tried Wicked yellow because they seem to have more pigment but it needed white base as well.
I documented a lot of my airbrushing in my JP restore thread.
