The following steps describe how to apply replacement adhesive in preparation for the resealing procedure.

Apply a little bit of high isopropyl alcohol (>99%) to a Q-tip or use a cleaning pad to gently remove the leftover adhesive on top of the Force Touch gasket.

To remove the adhesive on the edge where the display cables are running, fold down the display and carefully pull it away from the frame so there's enough space for cleaning.
