Black Gold Washes - Oil Washes That Is

Washes are used to accentuate panel lines and detail and to add a bit of interest to the surface of the model. Some say that you would not see any detail, least of all panel detail, on an aircraft at a distance away from the viewer. This may be true, but to me a model represents the full size machine and when you get up close to the full size machine you can see all the detail, including the panel detail. Again, as far as I am concerned, an aircraft model without a wash is quite boring. If it weren’t for the pre-shading it would be difficult to see the detail on the wing undersurface on the left in the picture (1). The wash is also an integral part of the weathering. One of the reasons I use artist oil colour is that, when it is wiped off, it leaves a very thin film of colour. This affect is enhanced at the next stage.

What to use?
Any medium can be used, enamel, watercolour, acrylics or artists oil colour, I haven’t tried acrylics, I think they might dry to fast, but each to their own. The main criteria are that the medium, or the thinner used, doesn’t affect the paint, or protective coat, that has already been applied. I have successfully used watercolour and enamel paints for washes, but I far prefer artist oil colour, for the reason stated above, and the ease of application. I use cheap white spirit as the thinner.

How to do it.
As stated in the previous article, “The Future is Klear”, I use Johnson’s Klear (Future) over the decals to protect them and the paint from the washes. Klear will protect from most mediums, but do test before trying something new.

Choose the colour.
First thing to do is to choose what colour to use. I try and compliment the paint colour, so I never use black. Black would undoubtedly accentuate the panel lines, but, in my opinion, looks totally wrong. For the undersurface of my Battle of Britain Spitfire, which is painted “Sky”, a greeny grey colour, I used Davy Grey. It’s at the left in the picture and has a greeny brown hue, on the right is Paynes Grey, which looks blue. (2)

Mix the wash
From what I have read and heard my washes must be much thicker than “normal”. The term tinted thinner is used a lot and my washes are much thicker than that (or my idea of tinted thinner is different). One of the reasons for this may be so my washes leave a film when wiped off, as stated above. I have not been able to get “tinted thinner” to work so this is the main reason for using more oil colour in my washes. You don’t need much wash to complete an aircraft model, so I mix mine in a milk bottle cap (3). I add an eyedropper-full of white spirit to the cap, add a dollop of my chosen oil paint and mix thoroughly. I then add a couple more eyedroppers full of white spirit. When I start the wash process I adjust the mix by adding more paint or thinner.

Applying the wash.
I use a No 1”bog standard” brush to apply the wash. Dip the brush into the wash and agitate the mix (4) (this is to make sure that the pigment is always thoroughly mixed), touch the brush to the edge of the bottle cap (5) (this removes excess thinner, from the brush). Touch the brush to a panel line on the model. Generally the wash will flow, via capillary action, along the panel lines. If it doesn’t then it might be to thick, so add more thinner to the mixture. The ideal situation is that the mix flows and leaves the pigment in the panel lines.

Sometimes it doesn’t want to flow, or flows only a short distance. If this is the case and your wash is the correct consistency, simply touch your brush at intervals along the line. You will likely find that it will flow in some lines but not in others, or not at all. This is not a problem, if when dry, there is sufficient pigment left in the panel lines to achieve the look you desire. I find that the wash will flow more readily in the deeper lines (6). Each time you go back for more wash agitate the mix and touch the brush to the side of the cap. Work your way along the underside until all panel lines are filled and all raised detail has the wash surrounding it. You may need to go back over some areas, either because you missed them, there had not been sufficient wash in the brush, at that point, or the lines need to be darker, such as the aileron and flap hinge lines. Once you are happy with the wash, leave it. (7)

You can continue to wash the uppersurfaces, but I, usually, use a different colour on the darker uppersurfaces. So I finish the undersurfaces first. The next stage is to wipe off the excess wash. Some suggest that you do it immediately, but I let this undersurface wash dry for 2 hours before continuing. This timing can depend on several factors, the oil paint I was using was the quick drying type. If using the normal type 2 hours may still have been sufficient, but it might have needed longer. Only wiping it off will give you the answer. You will see later that there is no rush, so don’t panic.
