all i can tell you is, it works for me. I just take a moist paper towel and wipe the fletch end of shaft. I you look at the papertowel after wiping you will see the graphite /carbon dust coming off. That way you are glueing to the shaft, not the dust.Then i just glue them down and they are tough. A lil bit goes a long way, cut a small hole and be very consrvative and careful, 'cause it is kinda runny. Once you get the hang of it, you will be sold on it.
