Hydrostop permanently treats new flies with a floatant. Coming in a conveniently large container hundreds of flies can be treated, dozens at a time. Flies allowed to soak for 5 minutes and then dried overnight will float higher when they are used. Perfect for yarn-type indicators as well as pre-treating dubbing.
