May sound off the wall, but I have always used a super-hold aerosol hairspray. I started doing this as a bicycle mechanic. Bicycle?!?! you may be thinking....Well, when you bang large mountains regularly jumping off of things from heights the bike was never designed to handle, you want your grips to stick....
An added benefit is that the hairspray has a respectable amount of alcohol. This allows the grip to slide on easily. This means you can easily adjust them while installing them. Once the alcohol evaporates, the grips are good and tight.
