Hey, recently I received my new rubbers , FH yinhe Jupiter 2, BH Palio ak47 blue. I’m not contemplating which glue to get, I’m hearing DHS no15 is good for Chinese rubbers and not to get butterfly free chalk I thought they were not too important but I guess I’m wrong. Any recommendations, also what is a recommended tool to cut the rubbers and should I definitely seal my blade right now or could I do it on the second time re gluing, thanks
