OK, a little context might help. My lad's learning classic car restoration, in the early stages but doing a welding and fabrication course. Hence we got a fairly rotten Midget. I think his real interest is in working with the metal, but by getting a car that needs a full rebuild he'll get to try everything and can make decisions from there.
We've talked about it at length and I think his plan would be to get someone else to do paintwork - the kind of kit/ environment you need to get a professional/ top end finish clearly costs a fortune. He should be fine with time to get bodywork through final stages of prep/ primer, but then pay for the finish. But, I'd like him to have a go at final finish, just so he's been through all the stages, and I'd like to have a go at it myself. In the end, the midget will probably be a keeper, something we rebuilt together, so the actual finish isn't crucial - so long as it looks ok from a few metres, it'll be ok
(We'll aim for better, of course.)
He's also clear that a compressor will help out in the workshop (apart from air tools, it'll be good for clearing metal chips from the lathe and mill etc).
So, the compressor would be used for general workshop use, application of primer, and (probably just) one bash at applying colour, til we realise we're hopeless at it. I'm not clear what paint to use, still trying to look into that.
Mike - that HVLP system review is great, thanks for the link. I think I understand what you're saying about it being the future now, but at the price for a good one probably doesn't fit the bill - unless he falls in love with painting at some point!
Point taken about cellulose, h-magic - thanks.
