When I was a kid my first job was in a body shop sweeping floors at the age of 12 then sand blasting then panting lawn furniture then on and on lol then I went to school in Indy for automotive did that for a wile then started building custom Harley's got bored and started selling used auto parts and that stuck so now I own a salvage yard in Ohio buy wrecked car for parts some I fix but must just part out that's my story in a nut shell so to answer your question I have had some training but most is self taught just have to have patience and with body work its like a broken record you keep repeating every thing you do one nice paint job you will sand the same car at least 50 times in different steps lol I think this old girl was made for a big block with some massive power the engine in the pics is just a mock up engine not the one i will run i will send them after its in and running
