Hi all, I thought I understood that when gluing something on a piano, you would preferably use something you can remove for in case you have to reglue, repair, adjust it or for any other reason. I also had the feeling that (when if works) CA glue would be quite hard to remove... Is there any easy way to break a CA glue joint, like when you put alcohol on hot glue - or am I wrong with the first assumption ?
