I love WWII armor and I build every type of model I can. The weathering products from AK Interactive are excellent choices for model building. I've only gotten the very best results and no failures from them. Aging and weathering a plastic model so that it looks real and on the ground used is an art in itself and AK makes the learning curve easy. If I goof up, it only takes a little paint thinner to correct. For great results in weathering, try AK Streaking Grime, use it sparingly and have fun!
