I have a Bart Reiter banjo too---and had the same problem. Not worrying that it might negate the warrantee, I heated up the end of a very small phillips-head screwdriver qnd touched it to the binding. That melted a slight indentation in it. I let that cool and then touched a sharpie pen to the barely roughened indentation. It works beautifully. (I did not get this idea from Martha Stewart !)
