Metal should be wet sanded to give a rough grainy effect. This rough grainy effect will help the paint to adhere to the metal. With metal actually being smooth the paint will have a hard time sticking to the smooth surface. This is why it is important to wet sand the metal first. A base coat should be applied to the metal before any airbrush art design is started. By acquiring the skills needed to do micro airbrushing the artist can capture more detail in their airbrush art on the model car. Imagine being able to create realistic eyes on a dragon you just airbrushed onto the hood of a small model car? When a person looks strongly at your artwork on the hood of the model car they can really see the capacity of the skills that you have as an airbrush artist. So to take care of your airbrush make sure that when you are not using your airbrush that you replace the needle cap back onto it. This will give a little protection to the needle itself should the airbrush happen to fall. A damages needle can be disastrous to your ability to create high quality art, because if you are unable to straighten a bent needle back out or the needle should break completely you will not be able to finish your airbrush art until you can get a replacement. Go to the library and check out some art books to help you get some inspiration to get you going again with your creative design. Sometimes by looking at other people's works you can get past your creative block and start creating your own airbrush art again. Any form of art will work to give you inspiration since after all you can airbrush any design you see. There is more that you can do with airbrushing that you can not do with hand painting. You can take airbrushing and create a beautiful mural on a concrete wall to turn that once bland wall into a work of art worthy of some attention. While you can do this by hand the time factor makes airbrushing a better choice. In this book she teaches the basics of airbrush art, airbrush types and how to set up an airbrush shop. The book covers such styles of airbrushing such as fingernails, automotive, t-shirts and even leather. In July of 2007 Shanteau released another book to help other artists learn the art of airbrushing.
