Flexible coating/sealant materials?
Make friction response inserts for a yoyo, on toy yoyos, the when the yoyo is pulled or binded (when there is string slack, when the response pad and string make contact.), the string grips with the grippy response (traction) and the spinning yoyo rolls up the string and returns to the hand..
Point is to make (my own, do-it-..myself) something and figure out what works well.
Not to buy something specifically for it that already exists, i wouldn't ask on DIY forum if I wanted to do that.
