I have been trying out a new airbrush – the Iwata HP-M1 – on my latest painting project. This is a small device, with a single action trigger and 0.3 mm needle. You set the paint flow by way of the adjustable screw at the back. I very much like the simple design, with the small number of working parts and faster cleaning time.  I had come to the realisation that for much of what I do my previous airbrush – the Iwata HP-B Plus – was simply overkill. So, for primer coats, base coats and varnish coats, the HP-M1 is what I will use. Of course, for fine detail work and more intricate camouflage patterns (if I ever do any!) the HP-B Plus is at hand too.
