I have also used locktite gel and others, which work well if you use it fast enough, where it does not go bad. I have been using gorilla super glue in the small metal tubes and this stuff works well. It stays strong and does not go bad as quick as the others. I think it maintains it's strength, because the metal tubes protect the glue from any kind of light. I think over time, some of the others go bad and lose that bond, because of too much light and oxygen exposure. These metal tubes are small enough and it seems that the glue stays fresher, longer. This is what works for me....
