There's nothing wrong with the tracks. they look fine as they are. Too many people make the mistake of trying to make them appear rusty. Rust they did not do. the alloy used had very little iron in it so rust was not an issue unless the tanks stood unmoved for very long periods of time. And this they did not do either. the Germans frequently had to drive their tanks from battle too battle due too the lack of enough rolling stock to move the Panzer units efficiently. That severely hindered there abilities to get from place too place i a hurry. It also attributed too the many mechanical break downs they had. Many tanks were lost from breakdowns just in transit.
