Zimmerit was a paste-like coating used on mid- and late-war German armored fighting vehicles during World War II. It was used to produce a hard layer covering the metal armor of the vehicle, providing enough separation that magnetically attached anti-tank mines would fail to stick to the vehicle. This paste is part of the Ammo zimmerit system, and will allow you to include authentic detail on your models in a variety of scales. 20ml tube.
