Many years ago someone brought me a bow to rehair that looked like it had silicone rubber used for the bow tip wedge? I was thinking about that today while rehairing a very poorly made bass bow that was more ready for the dump than orchestra use. The frog mortise was very poorly made and I had a devil of a time redoing it to get a wedge to fit properly. So is anyone familiar with this and is it silicone or do you need a specific kind of silicone. I am of course not talking about using this stuff on good bows, but this bow wasn't even worth the price of a rehair and I'd use silicone or anything else that would be more practical than trying to remake a poorly made bow. And how is it used? Do you put the hair in or put the silicone into the mortise let it harden and then remove.
