undercoat of green
The airbrush I use is an IWATA Eclipse High Precision. Its a double action brush which means you can control the airflow pressure and the width of the spray with the trigger. Not an easy skill at first , but once you get used to it easy enough. The paint cup is transferable side to side and I also have a range of large pots which I prepare with paint , thinners, cleaner etc and then just swap over as required.
If you are starting out with an airbrush you can choose a single action which give you a fixed spray - something like a Badger 200 a good solid starter. In case you don't know the difference between a spraygun and an airbrush . A spraygun sprays air into which paint is drawn by the airflow externally from the spray nozzle. An Airbrush mixes air and paint within the body of the brush and sprays through the nozzle which means as you can control both paint flow and air pressure you can get a fine line of spray if you want.
Anyway off to mix more paint
