And electrical contact cleaner works really good. Still good to wire them no matter how you glue them. I never used glue, only contact cleaner until I was "born again". Now I am just afraid not to glue. I use spray contact glue now, sparingly, or it takes forever to dry. Never had a grip fall off with contact cleaner though, or even get loose. To take them off you just pull the donut out a little and put in the contact cleaner nozzle ; give a squirt and a twist and voila, you didn't even need a knife, and you haven't destroyed your grip. :laugh:
