Well I finally tried out my 'safe' spraying set-up today. Not with 2K as I expected to get in a muddle today so did it with my epoxy primer. It's obviously not good to breath mist from it and last time I used it was with face mask but it doesn't have isocyanates in either component so I thought if I was getting the hang of my gear this would be safer then the actual 2K.
It all actually went quite well apart from I ran out of hooks to hang all the bits from (am spraying from suspension parts from XJ Jag) and I was surprised how comfortable the air-fed mask was and how the air coming thru seems very fresh but the major issue is the amount of air the mask is using. An alarm goes off when it drops below a certain pressure. There is a green zone on the dial on the belt and when needle drops below this bell rings and you're not getting any air till the compressor comes back up to pressure.
The (smaller) compressor for the mask was running nearly all the time whilst the (bigger) one I was using for the paint only pumped back up twice. I think I may try swapping them about but that's a bit of a pain as the big compressor is wired into the barn whilst the small one is plugged in with a lead running from my container.
It might actually be easier just to accept that the mask will keep falling short and leaving the paint area each time till the compressor catches back up.
Today I was painting about 25 small bits plus the actual front subframe so I wouldn't normally be dealing with so many bits and I reckon you get near 10 minutes on the mask so it would be enough time to do a panel or something, take a break outside, wait on compressor then go back to next panel and so on.
I only mixed up a very small amount of paint but was running out of things to use it on. Next time I could mix even less paint and just do less parts I guess.
One part I've been waiting to do for ages is an oil tank from a motorbike. I could easily do that in the time it takes the bell to start ringing.
Another grump is that the gloves I bought (latex iirc) are falling apart before even being used. They are either rubbish or have a shelf-life. I bought these because of the business about 2K getting absorbed through the skin.
It was all a bit rushed today as I got hijacked into doing stuff for someone else so by time I got to my stuff I was running out of time but determined to get it done.
Next time it will be the actual 2K (direct gloss black, not basecoat then clear) so I will have workspace perfectly set out for a smaller amount of parts and should be able to get the paint on without any lapses in air-supply
various part like this painted today. they were already done in etch primer from rattle cans

LIKE 
and when I got there I could see immediately it was smaller than my big one which was more good news
