Do it the right way
Whether you are installing grip on your own, or need your mommy to help you, it'll be easy, fast and will last as long as your stick
Apply foam tape around stick, put rubber ring on the top of it.
Put RocketGrip on, it should cover rubber ring and foam tape or use RockeGrip over old tape, before installing RocketGrip, check if whole grip part is covered.
Use boiled water or heat gun for installation, pour it over, starting from one side, still RocketGrip has fully shrunken.
