Thanks David, David LS and Jeff!
I always appreciate your feedback as you know! Jeff, a tanker like yourself can definitely judge if the scale cat looks like the 1-1 real tiger beast. I totally agree with you that armor requires different weathering techniques compared to ships and planes for instance.
Bottom line is that ships almost constantly got an ocean shower, planes were usually well serviced and taken care of by ground crew whilst tankers hugged Mother Earth so close that traces of Her stuck to the vehicle in the form of Mud! Furthermore, tankers like us don't even consider leaving the protective armored-box-on-tracks in the midst of battle just to give it a Car Wash...
This is why weathering will always be part of the life of scale tankers, trying to mimic the artwork of Mother Earth as realistically as possible! Armor weathering techniques are not harder to master compared to those for ships or planes but they are somewhat different.
