The rubber parts on this Leopard track was changed last year, and shows the wear and tear after one year of hard training
When I got home I took a curved model knife and a motortool with a steel brush attached, and basically slashed the rubber parts on the track as an experiment ( I have a spear track, just in case...). The result is on this picture which shows the difference between the original track (on top) and the one I gave the full treatment. I have not painted the tracks yet, but so far I am quiet pleased with the result.
I would love to hear if any of my fellow model builders have a clever method for making tank tracks look like the real thing.
