Any brand will do. For larger quantities, go to a good artists supply
shop. They will also give you reliable advice. BTW, acrylics differ from
enamels in that brush painting will produce a nice, level finish much
more easily, making airbrushing unnecessary in many situations. They are
also naturally matte, so that you may have to add a glossing agent to
get a satin or semi-gloss finish.
Resin castings must however be carefully and thoroughly cleaned first.
The best cleaner is an organic (citrus) based cleaner, followed by
washing up detergent, clean water rinse, and air drying.
The thinner used to make the paint airbrushable is a mix of alcohol and
distilled water, but proprietary thinners will have other additives. If
there is a thinner for the brand you choose, use only that thinner.
Others may work, but you can't be sure.
You can mix the paints to get the colour you want if it's not available
in the bottle. Not that an exact match matters all that much -- the
lighting used in your layout room will affect the colour anyhow, and in
real life colours soon fade and weather to shades different from the
IMO, consistency is more important than an exact match for rolling
stock. That means standardising on one brand of paint, and keeping
careful records of mixes. Use an undercoat to even out the colour
variations of the materials used.
For buildings etc, I find that brush-painting with colours mixed on a
palette is more than adequate, especially since it introduces those
subtle variations that make the building look more real.
Finally, an all-over spray of clear satin or matte after painting will
often give a better finish IMO.
I don't know if they are available in the UK, but I've used thinned
CeramCoat paints with success.
They come in crafty kinds of colors, but there is usually something very
close to mowt any color that you would need. They are pretty inexpensive
and some main colors come in even larger quantities. The only drawback is
that they dry absolutely flat; you would need to overspray the finished
product with something with some gloss in it to get the desired finish.
Hope this helps...
What he said.
I've sprayed Ceramcoat acrylics with no problems. You can use any kind
of acrylic paint in an airbrush (including latex house paint). One thing
that helps is to mix the paint with what's called "airbrush medium"
(made here in the US by Golden; suitable equivalent no doubt available
in the UK) to make it more spray-able.
And the other important thing: *Clean the airbrush IMMEDIATELY after
spraying.* Otherwise, you'll have one clogged brush and a mess on your
hands. (I keep a container full of soapy water on hand to attach to the
brush immediately after spraying to flush the brush before the paint
gets a chance to start drying.)
I hope that in a few years it [Wikipedia] will be so bloated that it
will simply disintegrate, because I can't stand the thought that this
I use one from Gumbacher(?). It is a bit expensive, but a pint-sized bottle
does seem to go a long way. Usually, I use about five parts paint, four
parts of the air brush thinner and one part water. A paint store friend of
mine tells me that if you use too much water to thin water based paint, it
does negatively affect its adhesion qualities. I've also found several
different spary products that will give various types of finish on the
