I guess it depends. When you're just starting, it costs a lot because you have to lay out more cash for paint and supplies. As you do more, you have more paint laying around so it doesn't cost as much. On average, it probably cost me $35-40 per body for the body and paint supplies. But that doesn't include the $$ I've invested in my airbrush and compressor and the amount of time it takes me to do each one.
