That’s pretty ugly. FWIW, I used to take a Q-tip with a bit of acetone to the inside of ferrules that were hard to slide on, quickly move them on the shaft while there was some slipperiness left and those things NEVER moved. Now it seems like everything I buy has a bigger ID, making epoxy a must. If I’m being honest, I think I prefer avoiding the hassle and just using a dab of epoxy.
