(Original source: Ultrawerke: Painting and Weathering Tutorial: Part I)
"While the scratchbuilt turret mold is curing, I think that I am going to start another tutorial about painting and weathering.
Although I normally paint my models with an airbrush, this is just for the very first stages. In fact, more than 90% of the work is done by brush. You definitely could substitute the airbrush with a soft brush, paying attention to not leave brush marks on the model, with the exception of soft edged camo patterns, you'll absolutely need an airbrush for that.
More important even than the airbrush, it's the compressor. You'll need one than gives you stable air flow, variable pressure, filters water and oil from the air and, if you don't have a suitable working space, be silent enough to allow working anytime.
This is mine, it is not the best of the best, but does all the above in a satisfactory way:
For the airbrush, I just recommend you to go directly for double-action, it is not so expensive and you'll notice the difference. This is my Iwata HP, I am extremely happy with it, worth every dollar I payed for it.
This is my cleaning station, it doubles as airbrush holder too. It's used to keep inside the solvents you pump to clean the airbrush.
OK, let's assume that you have already assembled and primed your model... I am going to do a battered winter camo scheme, but these techniques could be easily adapted to other paint schemes and conditions.
I start mixing the base color (Tamiya XF2 Flat White) with some gloss varnish (Tamiya X22 Clear) and adding about 50% of X20 Tamiya Thinner. The reason of adding varnish to the base paint is a) making it resistant to tear and wear and b) give the model a satin surface on were to apply filters and washes easily.
This is the model; a Ragnarok Vanquisher version (I don't know if GW ever thought about this, but I feel it's a very nice conversion ). I use the airbrush to build a little preshading over the darker primer. I spray more white paint in the center of the panels, leaving darker recesses and shadow areas.
This of course leaves us with an absolutely monochromatic resin chunk with no interest whatsoever. We are going to try to fix that.. using Filters!
Filters where developed by Miguel "MIG" Jimenez (if you don't know him, just make a quick search for his work, absolutely brilliant!!!!). They are like a kind of very subtle glazing done by oils or enamels. As oils can take up to 48 hours to dry, it is more practical to use enamels, wich dry in about two hours. Filters are prepared tinting turpentine or oher mineral spirits with enamels in about 95% solvent-5% enamels proportion. You apply them with a soft round brush (#8 or #6) but instead as is done on washes, you do not let the mix to run into recesses or crevasses. The good thing about the filters is that being based on mineral spirits, you can use them over an acrylic base as soon as it is dry.
I use the prepared filters from SIN industries. I am using here the blue filter (too strong color, by the way, I immediately changed my mind...). You can notice how the base color changes after the filter is applied.
In order to not turn your filter into a wash, you must soak the excess solvent before applying it.
Here is the result after two tan filters are applied (I let 2 hours pass before applying the second one, by the way).
Now we are going to fade the base colour. I first put some oil coulours in a piece of card. The colours chosen may vary, I felt these were appropiate for the white base. The colours used were from Van Gogh oils (left to right):
* Phtalo Blue
* Titanium White
* Naples yellow light
* Yellow Ochre
* Transparent Oxide Red
Now I make little points over the tanks.
May seem funny, but once you start fading them with the help of a clean brush with a little turpentine, the effect is subtler.
The finished panel.
In vertical panels, you should paint straight vertical lines instead of dots.
And fade them vertically too.
The resulting tank. Now the color is not monochromatic at all.
The problem with the oils is that I must wait 48 hours before using thinner on the model again.
As I am now limited to the acrylics, I am going to do some work priming the tracks. To make it faster, I am going to use the airbrush, and that means masking the surrounding area with masking tape.
I use Tamiya's masking tape for that.
It's a high quality masking tape (that means that it will not scrap the paint from your model once you remove it) that comes in four sizes.
The masked Vanquisher.
I'll use 304 Track color from Vallejo diluted 50% on Tamiya's thinner.
I spray it very carefully.
It's a real time saver.
Now I will start working on the base for the heavy weathered look I have in mind. I add 305 Ligh Rubber from Vallejo to the mix, as well as some drops of 597 Slow Dry to slow the driying process. The later allows you to work with acrylics as if they were oils, making possible very interesting transparence effects.
With the help of a good #1 brush, I start painting chipped or weathered paint areas.
I use also a piece of Scotch Brite to paint chipped paint areas faster...
The resulting effect is a good start for further work.
I also use a #4 brush with the bristles cut to 4mm. Now is when you notice the effect of the "slow dry" agent, as the paint is fluid, creates transparencies and does not dries up immediately, allowing time work with it.
This is just the first phase.
There is still a lot to do, but at this point I can not use thinner nor acrylics, so it's time to leave it dry during some time.
We'll continue working . . . onto part two: Amazing Weathering Painting Tutorial (Part Two)"
