I'm at the point in one of my builds where I am working on the stowage. To match the specific vehicle I'm modeling, I need to make a duffle bag, which is attached to the exterior of a Bradley, but got too close to the engine exhaust. Thus, the top part of the duffle got pretty well burned. I plan on making the duffel from scratch, using Kneadatite, which I will mold around a 'core' of aluminum foil (the foil will be wadded up to make a solid cylindrical shape). I can sort of leave the 'top' of the duffel 'open', where the burned part will be, but I'm at a loss as to how to make any 'burned parts' for the top end of the bag, and then what do I do to paint it, besides just black paint and possible black or dark brown pigments to simulate soot. Any ideas? I'm not that creative, but I can probably follow someone's directions or if anyone has a picture of how you may have done something similar... Help, please!!!
