That said, I don't have the keypad on my Bronco and hardly ever used them on any of the other Ford products I've owned.
My only concern about sticking anything on the hard top is if it starts cracking, Ford might say that the adhesive might have been a contributing factor. This coming from someone who's had their top replaced for cracks that occurred by some unknown cause.
IMO… unless you used something else, I would be concerned that the adhesive tape may not hold on the side of the hard top (especially with heat) because of the texture in the hard top?
