Several factors make Vibra-Stop different than other thread lockers. For one, it's an acrylic-based resin that doesn't have to be applied right before installation; you can brush it on a nut, bolt or whatever and then store the fastener indefinitely before use, with no loss of effectiveness as a result. Second, it's reusable; the manufacturer, Tectorius North America (www.tectorius.com), claims that a fastener coated with Vibra-Stop can be installed, removed and reinstalled up to five times without reapplication—although my experience with the product indicates that after four uses, its effectiveness diminishes enough to warrant recoating. Third, it works on plastic, wood and other non-metallic surfaces; this makes it ideal for applications such as small plastic screws in instruments and electrical components, as well as on other fasteners with soft, fine threads. Fourth, it isn't limited just to threaded fasteners; it also can help secure dowels, guide pins and the like. And finally, because it is waterproof and resistant to most solvents, it can seal the area around a bolt, stud or dowel.
