This is a trick I learned while cleaning my grip tape today. This is an alternative to slip tape, and 3M tape. Warning: This is for long boarders and skateboarders who simply want to protect their graphic from being sanded away. do not use this if you are planning to do any heavy board slides or grinds. if you end up messing up your new longboard I am in no way responsible. You have been warned. I will be doing my old sector 9 board for you today. I recently did this to my new apex 40.
