Airbrush art on the nails is not for the beginner just getting started in airbrushing. The work area is very small and the artist has to have mastered the techniques involved with airbrushing. One main problem that beginners face is over spraying. Over spraying is when the artist sprays outside of the area in which they are trying to spray. These are advanced techniques and will take you as an artist to the next level of airbrush art. Another way an artist can learn micro airbrushing is to work directly with an expert. Take on a workshop that teaches micro airbrushing and you can learn with some hands on projects under the supervision of an expert. Your airbrush will have a back lever as well that acts to shut off the air flow and paint flow when the trigger is released. If this should be come damaged then you could have serious problems with your airbrush. Don't worry though it is not hard to replace these parts should there be any damage. Your airbrush will have a handle on which you can hold onto the airbrush with. The paint can be automotive paint but make sure that you use a well ventilated area as the fumes can pose a health hazard. It is best when using automotive paint to wear a respirator at all times. When using automotive paint make sure that it is thin enough to flow through the airbrush. If the automotive paint that you have chosen does not flow then thin it down so that it flows. Another great way if you are doing this at home is to allow the design to dry then turn the shirt inside out and throw it into the dryer for about 40 to 45 minutes on the highest heat setting. After this your design will hold up to laundering. If you use a paint that does not require heat setting then you should still set the design. Prior to actually airbrushing the nails, a base coat should be applied. There are actually two reasons for the base coat. This base coat will help protect the nail from the paint and help the paint to adhere to the nail better. Metal should be wet sanded to give a rough grainy effect. This rough grainy effect will help the paint to adhere to the metal.
