Ok… there’s one thing that’s bothering me from these comments.
From the pictures, it looks like the primer adhered to the model fine. That means it is not a dirty model that’s the problem.
Let’s get specific. From the looks of things the primer adhered to the model but the white paint is not sitting where you want it over the primer.
I’m seeing what is called spider webbing, as well as pooling. Essentially you have two problems. The paint is drying too quickly in the brush, causing clogging, but when it works it is going onto the model too wet. The spider webbing happens when your airbrush is too close to the model and the paint is still wet.

Angel Giraldez (pro-painter, known for a lot of great work, including the box images for Infinity and other model companies… has two great instructional books out, in fact) sets his PSI at about 24. However, he has top of the line equipment, thinners, flow enhancers, etc., so play around with lower and higher pressures and see what works for your situation.
As for the spider webbing and pooling, as I said earlier, try more thin layers and don’t hold the brush too close to the model.
Also, what primer are you using? I’ve had some that worked much better than others.
