Perry, rule number one, start as you mean to go on, read the manual which comes with the air brush. Get to know how it operates, learn how to clean it and keep it in top working condition. I know you intend to build trucks so, seeing as though you will probably want to perfect a gloss finish, I would suggest that you learn how to thin and spray Humbrol enamel paint. I'll have a look through my library and let you have the details of a couple of book titles which may be useful to you.

Air compressor and air brush turned up today all looks very good had a quick read through the manual and a quick test with no paint. I do have some humbrol enamels but not 100% sure what to thin it down with and at what ratio. Ive looked around and I found the thin down to milky consitoncy to be poular but everyone thins down with diffrent fluids a point in the right direction would help if posible cheers guys Perry

Hi Perry different people use different ways and thinners but to start with use Humbrol enamel thinners with approx 50/50 mix and stir thoroughly Dave

You need to thin the paint to the consistency of milk, however, temperature will play a part in the eventual finish you achieve. Start with attempting to draw lines on plain white paper with the brush at different thicknesses, note what happens at various distances from the subject your painting. If your compressor has a air gauge, attempt to keep your pressure at approximate 2 bar.

... every so oftern when i would start painting it would spit the paint first Perry, my guess is that the mix is too thick or the pressure is too low.

Hi Perry, I'm fairly new to airbushing, but have done a bit now and have encountered some of the problems you describe above.
I'd agree that the biggest problems seem to be related to paint thickness/consistency. I use Tamiya and Revell Aqua acrylic paints, so it's relatively easy to thin down down with acrylic thinner or just water. The compressor air pressure can also affect the spraying quality, but I've found I generally need to turn mine down fairly low, but plenty of experimenting and practice spraying will help you to gauge the most effective pressure level for the paint you're using. This is also related to how far away the brush is from the surface being painted, again practice and experiment first to establish a comfortable distance to get the best finish and adjust the pressure accordingly.
I would also add that my airbrush and compressor are about the cheapest and most basic you can get, but still can give very good finishes if set up correctly, so don't be put off by thinking cheaper ones can't give a good basic finish. It probably won't do fine lines but using masking techniques will get around this, which I believe are explained elsewhere on the forum. Hope this helps. Rob.

I think I got it today a bit of practice and tweaking I found the best for humbrol enamel was a 50:50 mix with thinner at about 18 PSI. I also have one of the cheapest air brush/compressors but im impressed so far
