I'm building a motor pool diorama and so I would like to know how do you make the pad marks on the road and concret surfaces that are made from armor vehicles such as tanks and other tracked vehicles?

back when I was a kid we used to make printing stamps from a potato cut in half and carved to what pattern we wanted to stamp. You counld try that. or if you are replacing the kit tracks you could use the old rubber type and just make a short length and apply paint.

You can always use an unused piece of track/tire for stamping purposeses.
