Single application (0.5ml) of KlingOn Rearview Mirror Adhesive. Equalizer KlingOn Slingle Shot Rearview Mirror Adhesive has a squeeze-on primer. The adhesive has a gel-like consistency to keep it from running down the windshield. To use KlingOn, clean the glass and mirror bracket thoroughly. Apply the primer on the glass where the bracket will be installed and then apply the primer on the mirror bracket. Let the primer dry then apply the adhesive to the bracket. When you are ready to install the rearview mirror bracket, be careful to place it exactly where you want it. Be sure and wait 3-4 minutes before installing the rearview mirror back onto the bracket.
