For some time now I have been meaning to have a go with a microbrush. I'm sure they've been on sale for years, and been used by thousands of modellers for all sorts of useful things, but I've never had a go. Until now. By applying a very small amount of wash from the tip of the rigger brush, I was able to just about colour the tiny bristles of the microbrush. The tip was then poked carefully at areas of the car where I thought rust would form. I have no photograph of a rusty SunbeamTalbot 90 to work from, so have guessed where the rust might form by recalling all the work I had to do when 'fixing' my own cars all those years ago. You can see where my guesswork placed the rust in this photograph, and if anybody knows that it's in the wrong place(s) then please let me know.
