While practicing it is better to use a simple black paint. The only thing you need to be doing is experiment with the airbrush. Practice spraying the airbrush on a cheap surface while you learn just what pressure is needed and where.

Once you are comfortable using the airbrush then you should work on creating shapes with your airbrush. Using a cheap surface airbrush circles, triangles, squares and rectangles. While this may seem stupid it will help you to learn how to create designs using your airbrush. Continue to practice with shapes until you are able to perfectly render airbrushed shapes.

Once you have the ability to render the shapes, you can move on to rendering shapes in different textures. This means that you should work on creating shapes with thin lines and shapes with thick lines. This will help you to learn more how to use the airbrush to render broad designs as well as fine detail.

Practice using stencils on a cheap surface, still using your black paint. You will also gain knowledge from trial and error on how to remove stencils without disturbing the paint.

Stick to ready to use black paint from Golden Airbrush Colours because it really does not matter how the paint looks at this point. The only thing that matters is that you learn the basic techniques so that you have a good solid foundation of skills in which to advance you forward.
