Do they adhere well to the surface after they dry? Do they rub off at all like some enamel model paint? Or do they permanently 'stick' to the surface? Would really love to try these out, if they work as good as people suggested. I sometimes use enamel washes for plastic models weathering, but they are only good for looks since they get rub off easy by fingers if handled too much (unless you seal it with a clear coat...but don't think that is good for fabric uniform).
