Does anyone here use the airbrushing technique for Imperial Guard Tanks? What with me doing an Armoured Battlegroup, I'd like some advice. Tanks in advance. (God that was an awful PUN)
Hmmm. That's a pretty broad question. There are as many factors using an airbrush as there are with painting with brushes.
First off, do you already have an airbrush or are you planning to buy one? If you plan to buy one, get a good double-action airbrush and compressor. One example is the new Iwata Revolution. Get a gravity feed (the one with the cup on top) and not a siphon feed (bottle on the bottom). The siphon feed uses too much paint to be effective for miniature painters. Gravity feed let you add a drop or two per use.
PRACTICE!! before you start painting your minis, practice. It takes just as much practice with and air brush as a hair brush. (return PUN)
Make sure to try different thinning techniques with your paints. Its amazing how much difference a mix can make. Don't use water to thin. It beads up and ruins the adhesion of a thinned spray.
Practice some more.
A compressor is your best bet. It's more expensive to start but you will be much happier. Get a piston oiless compressor and not a diaphram compressor. Complicate reasons, just trust me on this. Also, you want a one with a air tank. It helps keep the spray even. Make sure you use a moisture trap in your line. I prefer two. You can use compressed air from cans, car tires, propane tanks, etc, but you'll be MUCH happier with a compressor.
Start out painting uniform, smooth primer and base color coats. Then move on to shading and details. Practice some more.
Unless you have garage or other windless area outside the house, you'll need to build a spray box. These are cheap. Just use and large box, hook up some dryer hose to it with a fan at the other end, and vent it outside. Even if you don't mind the smell/spray of acrylic paints (and they aren't as vile as solvent based paints) you will end up with a find dust around the house from overspray. Set up a spray booth. Painting outside is almost impossible since the slightest breeze can mess up the detailed fine spray used my mini painters.
If you can set up near a window, run the paint booth exhaust out the window and, using a long air line, run the compressor outside as well. Just the airline comes in.
That's about it to start. If you have more specific questions just ask. Oh yes, practice with your airbrush before you use it on a mini.
Yes, I was thinking that I should test on some Cardboard or something first. Tanks for the advice (Counter-PUN ).
I don't own an Airbrush, no, but I do plan to buy one (From where I don't know).
Sadly, I don't live in the U.S, so I shall have to search local places. ^_^
Cheers for the help anyway.
Just a dissenting opinion here -- I think that a single action brush is better for modeling, particularly for new airbrush painters. Double action brushes are much more expensive and more difficult to control. Plus, you don't really need the variable pressure with a model as you would with a painting.
I fully agree, though, on getting a gravity feed. I use a siphon feed, and it uses up a LOT of paint. I also fully agree on getting a compressor. They're noisy, but buying cans of air gets really expensive in a hurry.
I'd agree with everything that WolfRaider said apart from the moisturee trap maybe. I live in Ireland and the air is humid enough and I have no problems without one. Its just that I thought those things were really expensive, so if you're not going to use yours a whole lot then you may be better off putting the money elsewhere....
Practice, Practice, Practice. And Clean. I ruined two airbrushes when I started from not cleaning them and the paint clogged the insides. Start with a cheap one and when you get better move up a class, and so on. Hope it helps.

I thought the point of a moisture trap was to stop atmospheric moisture that condenses in the compressor from finding its way up the airline and causing your airbrush to 'spit'. Nothing really to do with the humidity of the atmosphere.
Good advice already in this thread, don't think I can add much to it.
However, do try to get an airbrush that is easy to strip down and clean. Certain components may be worth having as spares too, namely air washers and possibly needles depending on the model and precision.
