Good job and welcome to the club! If you're afraid to spray color, or are starting out and don't know what the knobs do, etc., spray primer on a body that needs it. Learn with primer and you can't go wrong because you can sand it away if it's too much or get drips, spatter, etc. Also, get an airbrush specific for primer, and another for color. Primers are .5 and colors are .2, .3, and .5

Another tip I can provide is use paint that is pre-thinned for airbrushing and stick with that brand. I use MrColor and Alclad primer, Alclad chromes and metals, and 3 types of colors - Number5, Street Blisters, and ProScale Paints. They're all exceptionally well for their task.

Have fun!
