how to stop loosening of a head band
Is there something like the opposite of WD-40, that is a spray with nozzle and will cause friction instead of removing it? Other ideas? I have this light and magnifier headlight I like to use, but the knob I turn to tighten it does not hold its place well. It is like the knob in the headband of a hard hat, turn clockwise to tighten the band, counterclockwise to loosen, and it has click stops but they are very weak. When wearing, the tension of the plastic band is enough to make it pop loose while wearing.
