Compressed air hammer for body construction parts production? – other Spiezial tools?

Hello, is there something like an automatic hammer (set) for the body construction? At the moment I have alienated myself from a compressed air mousse purpose, but if there is something better, I am quite ear! I want to make complete car parts with it, as see photo. Also, where can one buy for the body construction tools, which for example can not be found on the Internet? – Is there a real secret tip?
