Halifax Posted August 16, 2018 Share Posted August 16, 2018 Hey, All: My concertina has Delrin buttons and sometimes they seem a little slippery. Or maybe it's my fingertips that are smooth and worn from all the typing I do on the computer? Anyone ever consider using a tiny bit of rosin or something to keep fingers from slipping off buttons during the fast bits? Or is it just me? Are bone and brass also slippery? Thanks.
