Get some breathing apparatus fire-fighter style - £120 for the equipment, £4 for an inspection and refill at a scuba shop and it gives 35 minutes of positve pressure safety.
I got mine here:

I imagine when a company literally has to guarantee your life a lot of R&D using the best (expensive) parts puts the final sale price up?

I agree, but for some people, me included, it's a viable option.
What size compressor do people run the air-fed masks with (without spray-gun)?
Robot, possibly true, but they're such basic plastic & foam things, bar the activated filter pack. Since they rely on positive pressure there can't be masses of research really? Although maybe regs come into it. I'm sure my bike lid had at least as much if not more R&D, and it cost less. It's the way they are anyway, none are massively cheaper than others.
Comps - I borrowed the missus' Aldi 2.5/24 but it couldn't cope really. Ran constantly, far outside of it's duty cycle I'm sure. Ended up buying another 3hp/150 from Shiremoor. No probs now, and enough air for blasting.
I just can't see 35 mins is enough to do much more than a quick job, clean up and go. Certainly not enough to put a mist & couple of wet coats onto a car. Not to mention the thought of trying to get all around a car with a tank on yr back.

Nope, though I've spoken to someone who's used it on their project and read up all the posts on here also contacted a supplier who has sold them to people for use with dangerous paint. The kit gives a sound indication when the pressure starts to drop too.
Now, suddenly not seeming like the brilliant idea I thought it was..... 35 minutes isn't long if you take into account mixing the paint, ******ing around with the spray-gun etc. Maybe an extra tank would be an option.
Edit: This mask on Spray Guns direct uses very low CFM http://www.spraygunsdirect.co.uk/product.php?products_id=6778&oscsid=nstqch38kfenibt49pg9hejgb6 so would it be suitable for use with this an eBay Wolf cheapo 3HP compressor which should be 8-9 FAD ( http://www.ebay.co.uk/itm/Wolf-Chey...Air_Tools_and_Compressors&hash=item56483f8499 )?
So a full set-up with filters would come in at £400'ish which would be reduced with a 2nd had compressor. Which isn't bad at all considering the breathing apparatus is £120 for 35 minutes or £200 for an extra pair of tanks to give 115 minutes and would involve stopping mid-flow.

That's the thing, everything's got to be A1 to get in & out in 35 mins, plus having to get down to sills & valances and all that clambering about low down.
Comp might be OK, prob better with a belt one though, they usually go to 150psi and are lots quieter too. The thing with masks is the air is constant so say 6cfm doesn't sound massive but the comp's got to give that the whole time, no pauses like with a spray gun. I've linked mine so's they help each other out.

If I was to get an air fed mask I'd do the spraying in a barn inside a carport tent with the compressor 20 meters away in a seperate wooden garage outside the barn (across a dirty water ditch).
The spray gun compressor would be outside the tent in the barn and is a petrol 3.5 HP unit, old as the Earth, I was planning on using LVLP guns with or HVLP though the CFM needs of these seem to vary massively.
Would you recommend the 100l 3hp you got from Shiremoor for the air-fed mask with the compressor situated at 20-ish meters away? Or should I go bigger if I go air-fed?

Power-wise, I think 3hp is about the biggest you can get on single phase, sensibly. There's twin 3hps and 4hps etc but they cost so much. Reckon if buyng one may as well get a 150 tank, the more the merrier.
Don't know about that distance but seen tables somewhere with pressure loss vs hose size and distance, might help, and probably someone on here knows the score with setups like that too.

I'll have a nose around and see what I can find, cheers for the advise Chipper 
No worries
Just for the record btw I'm a DIY-er. Gary at Shiremoor would say get the newest cleanest-breathing comp you can, for longer-lasting filters (some in the triple-filter-pack are consumable, plus the mask one). But hard lines & drops clean it up massively anyway.
The gear does cost, but compared to a pro spray job it's well worth it, and looks even better a down the line. By which time the missus has forgotten about it all too hopefully
