How to be an Armoured Farmer, building Hobart's Funnies in Glorious 15mm (and maybe 28mm if they arrive in time!)
Essential bits and pieces
First up the compressor, I got this one from everything airbrush. it is essential to get one with an air trap, regulator and storage tank (called a receiver). 
Compressor details for those interested. When I spray base coats I tend to set it at 25psi. For laying down colours I drop it to @20psi depending on how the paint flows; and if I'm using the finest needles and close up work it will go down to 15psi and as low as 10psi for the finest detail.
Protection is not a dirty word! I always use a facemask when spraying, even though I never spray without the extract booth on. The best you can get without going for a half face mask (which are expensive) is an FFP3 disposable mask. These are the finest micron disposable ones and are designed for asbestos use, so pretty good. I also use a glove for my non-spraying hand so that any overspray doesn't get on me.
Lastly somewhere to hold your airbrush, this one also doubles up as a waste pot for when you want to clear through your airbrush with water/cleaner.
