cpanther1995 But will Flexseal dampen vibration since it’s rubber better than Epoxy?
I don't know if either will provide much dampening. If it does shafting epoxy will still flex some compared to zero with hardware store epoxy. I took out the polymer face from a putter since I felt it was too dead feeling. I wanted the crisp feeling of brass so I fabed up a brass insert and glued it in with shafting epoxy. It still felt dead. It dawned on me that shafing epoxy has a bit of shock absorption properties to it. I took the insert out and glued it back in with JB Weld. Bingo, hard as a rock with a nice crisp feel.
