I can attest to the fact that this is the only way I've ever used. Aqua Net or Rave hair spray, the cheap stuff works best. Spray the double-sided tape, tape to where you leave 1/2 inch clearance from the bottom of the tape to the bottom of the grip, douse the inside of the grip and the tape in hair spray, twist to fit how you want, wait 24 hours, them grips never moving
