I'm no different from many modellers. While scratchbuilding or assembling kits of all shapes and sizes never puts me off, painting and its many phases and methods is always the source of some anguish… So I tend to postpone the job and unpainted parts pile up in a box. When the box finally overflowed, I jolly well had to get down to the painting stage! Amongst the unpainted parts, I happened to have a couple of small Renault FT tanks, and this led me to take a closer look at the methods used by our fellow military kit enthusiasts who work in 1/72 scale. And it turned out that a number of techniques and products they use are perfectly suited to railway modelling.
