I bloody love these water mixable oil paints that I've been using!
I thought gouache was the wonder stuff, well it still is really, but these oils are even better and much more versatile. It's taken a while to figure out how to use them effectively, it requires a slightly different technique to gouache, but I'm now glad that I've persevered with them after the initial disappointment that I had.
I've used them quite successfully, I think, on a couple of the TTA wagons that have graced the bench of late.

Pretty much all of the barrel weathering, with the exception of the streaking from the filling hatch, has been done with the oils on this one. The streaking is gouache, which is still the best method of achieving this kind of effect. The underframe is a mix of the oils and powder/hairspray, with additional powder used dry on top for variation. The powder/hairspray mix was usd on all the black bits of the underframe, with highlights and other colours added as required.
The oils are great for adding subtle variation of colour, as they can be added sparingly and spread around, quite a long way, using a stiff-ish flat brush. They do dry pretty permanently, unlike gouache, after a period of time but the finish is still relatively fragile. They need to be sealed with varnish if the models that they're used on are going to handled regularly.
They can also be used in wash form, with either white spirit, or water with a drop of screenwash in the case of these particular paints. They can also be used in a form of dry brushing to add very subtle highlights.

Again, the barrel weathering is exclusively oils, including the spillage stains. So far, I've not found anything quite as good for doing subtle weathering as these, especially with the ability to add extremely subtle variations in colour.
The oils aren't as opaque as gouache, so they're no use for the heavier effects, for example I tried them on the truly filthy ex Esso tanker, as seen a few posts ago, and the oils wouldn't cover the original livery, even brushed on neat. I ended up using the gouache for that particular model, which reminds me that I must finish the other side of it!
This is probably going to sound a bit pretentious, but I think these materials allow the boundary between modelling and art to be blurred a bit. To explain, part of producing a painting of a wagon would be adding the highlights, shadows and other subtle variations to bring the subject to life. In a way, weathering a model of wagon works the same way, except that the wagon itself is the canvas, if you see what I mean. I am definitely no artist, but am using these paints in almost the same way as one would, I guess.
Still, whichever way you look at it, I'm pleased with the results so far, and look forward to seeing what else I can do with this stuff. More soon!
