This Permatex Rear Window Defogger Electrically Conductive Tab Adhesive Kit (21351) is designed for car owners seeking a reliable, low-cost solution to repair broken defogger tabs on their rear windows. It provides a strong, electrically conductive bond to restore defogger functionality quickly and easily. A key caveat is the temperature sensitivity during application, requiring a specific environment for optimal results.

The repair should only be performed when temperatures are between 50°F and 75°F (10°C and 24°C).
The adhesive requires a full 24 hours to cure before the defogger can be re-attached and activated.
This kit is specifically for bonding defogger tabs to the grid. It is not designed to repair broken conductive lines within the grid itself.
The kit typically includes a Cleaner/Activator Towelette and a tube or packet of Electrically Conductive Tab Adhesive, along with instructions.
Touching the activated surface can interfere with the bonding process, potentially leading to a weak connection or failure. It's important not to touch the mounting surface of the glass or the tab after applying the activator.
While it is an electrically conductive adhesive, it is specifically formulated and intended for automotive rear window defogger tab repairs. Its performance on other applications may vary and is not guaranteed.
This kit is suitable for most standard automotive rear window defogger tabs that attach to a conductive grid. Ensure the tab you are repairing is designed to connect electrically to the grid.
Ensure the tab makes complete contact with the conductive grid. Check if the adhesive has fully cured for 24 hours. Verify the wire connection to the tab is secure. The issue might be with the defogger grid itself or the vehicle's electrical system.
Verify the application temperature was within the recommended range (50-75°F). Ensure the surfaces were clean and dry before application. Make sure the tab was held firmly in place for the full minute during application. Avoid touching the activated surfaces before applying adhesive.
This kit is designed to reattach a tab. If the conductive grid lines are significantly damaged or broken, this adhesive may not be sufficient to restore full functionality. Separate conductive repair kits or professional assessment may be needed.
