Iv heard that most metal bands are actually christian in religion, but im just curious.
This would depend on the type of metal somewhat. In my experience, gorilla glue does not work real well with metal to metal as it is not porous. I have used it to glue metal to wood and it works well with sheets of non galvanized steel to non pressure treated wood. For small metal pieces, it would probably not work well as gorilla glue also expands alot, and is not flexible at all. What I would recommend if this is something decorative is to check into having it soldered, if looks aren't an issue and it has to bear a load check into having it welded.
