I started airbrushing last summer. I have an Iwata airbrush. I own The Ultimate Airbush Handbook which you can find on Amazon. This is an amazing book with beautiful photos. It talks about airbrushing on paper, sculptures and many other mediums. I started airbrushing sculptures and did one pyo keeper dragon using airbrush. It is really a lot of fun and you can get some amazing results. The book I mentioned as well as various airbrushing forums can help you with what you need. You need to have the correct paint or mix paint to be the correct thickness so it will spray from the airbrush. You need to know how to clean the airbrush well, among other things. You also need a good air compressor which I’m not sure if you have yet or not. I think you’ll have fun, just pick what you’d like to airbrush and the possibilities are really endless.
