A while back I had a play at weathering a BR Blue Class 37, mostly in order to cover up the difference in colour between the Bachmann blue and the Phoenix blue I had sprayed the new components with.

The end effect just wasnt good enough, looking more like a thick coat of powder/hairspray mix than weathering!

So I've had another go.

I have started off by using a flat brush and lots of water to remove most of the powder mix, leaving sooty deposits around the exhaust and dirt build up in panel gaps and against raised detail. Once that was dry I then attacked the roof with Tamiya powders to blend it all together.

Moving to the sides which were not touched last time I added a coat of the Tamiya browns to the whole side then gradually removed it, the aim being to build up dirt around the grills and the tumblehome. Again I think the colour may be a tad on the light side here, will need a going over with a darker brown at some point I think. That said, the loco is intended to be modelled working on China Clay, so to some extent light coloured weathering is rather fitting.

Once this is properly dry, I plan to dig out some gouache to add a few darker patches were there is run off from roof detail.

One area I am really not happy with is the yellow end, just cant seem to get the right effect there. Gussing that its probably a case of needing to use a different method.

The bogies have just had a light going over with the powders so far and again dont really look the part (it was more a case of just wanting to get them away from being shiny and black). Again not too sure what I will do here.
