1st of all everyone in wasteland stinks... at least most of regular people do. Taking bath is pretty unique thing out there, isn't it? 2nd when there is a fight you don't wait with looting until your enemy's body starts to decay. Gunpowder or blood are a bad joke, only thing that could work like negative effect are guts from gore deaths but still only thing you need to do is to remove it and "clean" it with some sand or something like that and you have pretty nice armor once again.
Yes it "could be" but whats the point? Make PvPers wait 1 day until they sell the stuff? I'm all for little detail features, but this one stinks.
