>>6544448Keep in mind the crews didn't have airbrushes either (for the most part) they probably would have painted with a brush by hand I know quite a few sources described the german basically taking a broom dipping it in what ever they where using as camo and then beating it on to the tank. To recreate such a thing this method may work for you. I know it's about late war germ tanks but the methods would still work if you just altered them to your need
