Painting white....

I am having trouble airbrushing gloss white. I'd be happy with even flat white at this time. Its on a '53 Corvette, but I had similar (but not as bad!) problems with an S3 Viking; and even more problems with an NCC 1701.

Does anybody have some air pressure, dilution, paint, airbrush type settings that they have found to work?

Right now I am getting a pebbly finish, and it's cracking. Over the last 18 months I have tried Tamiya gloss, flat, Model Master and Polyscale reefer; through Pasche H, Badger 200G, 100G, Iwata Revolution; and dilutions from straight out of the bottle to 90%.

What I experience is that there seems to be almost no "sweet spot" of just enough dilution. Too much it's thin and spiders or doesn't cover, too little it's pebbly. The only other color I have nearly this much trouble with is yellow.

The closest I have come to an acceptable finish (on the hood) is with brushing. This ends up with some unaccpetable waves/valleys, which I am able to sand out using varying wet/dry sandpaper down to 4,000. Looks great, but I'm sure I can't do this on the body around the little details(windshield wipers, accent trim, tail lights)

I asked this question on Car Chat and the responses so far have been "use Tamiya Neutral Grey Primer"; Ok I admit I did NOT prime the model!!! But I did spray a bazillion thin coats of white; and wet sanded it down to 4,000 grit. It looked fine, but with an uneven color to it. I am stuck at the final finish coat. With all the coats I've put down I should be an expert at this by now; but I actually think I've gone backwards!!! The S3 turned out ok, just not very glossy. This looks worse every time I try something new

Thanks for your help!
