On a recent holiday (one of many reasons why there has been a lack of posts) I was reading about the recently introduced AK Interactive Weathering Pencils. They struck me as a potential solution since the way they work is that you rub on the pencil as you would with any crayon but you can then spread it out and work it into crevices using a damp paint brush.
If you really don't like the result then you can use more water and wash it all off completely. Here are some examples of what I have achieved so far.
It's a mixture of smoke, rubber, dirt, earth and sepia. Due to shortages of the packs of six I splashed out on the complete set, probably excessive but it did give me the chance to experiment. Interestingly I didn't like the effect I created on the roofs so I dampened a piece of kitchen paper and wiped it off, creating a better effect than expected!
They can probably take some more layers and there is definitely a technique to getting the dirt in the corners but I think I will persevere.
