I have used the look before, someone at school had suggested sponging, it was a wierd idea, but after thinkign about it, it could get a look, i think fornow though im doing dry brushing and spray on dust. I would to the black over sliver but my pack is kinda done, so now im weathering it, doign cosmetics to the looks. Oh i did this very interesting paint job on it. The pack is flat black as always but then with silver spray paint, step back and spray the pack, if doen right it will give it a very cool silver dusting. I did that to my pack first, it looks great, next is drybrushing, then dust. I can't wait to post this thing!
