Just some fun for reading:
I'm about to venture into spraying 2K for the first time.
I had friend who is now dead from exposure to nasty stuff in his youth (25 years to catch up with him - but it did !!) - so am adamant that I will opt for maximum protection.
I totally balked at the additional cost of buying a second compressor, + airfed mask, + triple oil/air/coelesc. filter setup + extra hoses & fittings etc
In addition to which, the only place to site the 2nd compressor for the air-fed supply, was about 20feet from the garage entrance - so not really far enough away from drifting isocyenates etc.
I did some research on BA rigs (as used by the petrochemical companies for safety/exposure etc) and have decided I will swap/adapt the 300 Bar "Demand Valve" (tank/cylinder connector) from a chemical BA rig to fit my scuba cylinders (not hard), and have a 100%-guaranteed-isocyenate-free air source, with a full-face-skin-tight mask to eliminate skin exposure, with 2-3 hours worth of air supply per 12ltr scuba bottle, based on 1ATM consumption calculations from scuba experience.
Here's the BA rig I bought from ebay (I already own 4 x Scuba bottles, giving me 10-12'ish hours worth of clean air).

£65 !!!!! and a little bit of messing about (I maintain & service my scuba regs etc, so am happy to shake a spanner at the BA rig) - a LOT cheaper than original method.
Scuba cylinders can be had for £30-60 2nd hand - check ebay (ensure they have a current test certificate/stamp) - and cost as little as £2 to fill, so this is a really viable alternative for me (I live on Guernsey so scuba centre is 5 min drive).
Will post pics (vid?) of setup shortly - should give someone a giggle !
