Where do you guys get those ideas? Cola, gums, wd-40?! Easiest wait to put foamies on and remove is with water. Make sure your bars and inner side of girps is clean, so they could stick good together and just soak grips with water. They will get on easy, will remove easy just as well. Only 1 minus is that you need to wait till the water dries, after that, they are like glued. Been using this "tactic' for quite a while now, not even thinking about changint it. Cheers
