Pressure/ friction holds the grips in place as they are always stretched over the surface. 2 way grip tape etc is only used with solvent to get the glue slippery to get the grip on. It does not actually hold the grip in place.

Is that right ? I have asked that exact question of every grip fitter i have ever met and was always told that the adhesive on the tape took effect as soon as the solvent evaporated.I can feel an invention coming on!
