I have new bass (yay! ;-) ) but it's endpin rubber is not that great. It's the one that you wind up on the thread. Thing is, that it's unscrewing a little after few minutes of playing and starts buzzing on some notes. During practice I can tighten it, but would like not do that during a gig. I will replace it eventually, but do you have any ideas with what to smear the screw to make it stay in place better? But nothing permanent, because I will replace it in the near future.
