Minimal for painting?

[WyattTX]

I am thinking of attempting painting. I plan to practice on a battered work truck. I have a large air compressor, and a decent size building. What tools would I need at the bare minimal for paint and body work? I am not looking to spend a large amount of money, as this might be the only time I do this. But I dont want the end result to look like crude trash either. Thanks for any advice.
