Wear and tear is usually a welcome addition to most vehicle models. After all, tank armor is made to take a few hits.

One of the things to keep in mind when painting something like that is the story it tells. Where and how you place it tells of how the damage happened. Rusty areas are older than shining metal showing through- moreso if there are streaks of rust leading down. A combination of rust and metal shows that this is a place where the rust layer gets scrapped off.
