High cfm compressor or turbine, hoses, hvlp gun, maybe a pressure pot like Rich said or a Binks down at Sherwin. Be prepared to spend mucho dollars though if your not making your own.

This one is 5gal but you can piece together the harbor frieght 2.5 gal pot kit and their sprayer to your compressor and be up and spraying in no time for a little over a c note.
