This is a medium strength thread locker and sealer that will work even if there is some oil on the threads, as there always is. In the real world none of us has the time to get all the grease out of the threads of a nut or bolt, so this is the solution. Clearly you don't want the threads filled with oil, but they need no more clearing than a wipe with a dry rag or wipe.

There is a common misconception that thread lock is only about preventing fixings coming loose; in reality it is also used to seal the threads which is of huge benefit on motorcycles. In many positions on a bike you have either stainless or mild steel bolts, screws etc in aluminium alloy components. Combined with moisture this sets up bi-metal galvanic corrosion, which is very bad news. This results in the destruction of the alloy threads causing weakness. If the threads are coated with threadlock and seal before assembly, the threads are sealed against the ingress of water. We always use thread lock and seal even if using spring washers etc.

Although buying smaller bottles is more expensive per ml, you don't really want to buy more than you will use in a year. Storing glues and thread locks in the fridge will extend the shelf life considerably.
