you need at least a 60 gallon two stage compressor. with that you will also need a filter to trap the moisture, and probably a desiccant snake. Some other things you will need are body filler, putty, primer, masking paper, tape, razors, tack cloths, mixing pails and sticks, proper ventilation system, proper lighting, a carbon mask if you're not gonna buy a fresh air system, rags, reducer, wax and grease remover.
