Permatex part number 21351 is an electrically conductive tab adhesive designed to reattach defogger tabs to the defogging grid on a rear window. The adhesive restores electrical continuity at the tab-to-grid joint, bringing a non-functioning defogger circuit back into service without replacing the glass or the entire defogger assembly. The kit is intended as a complete, standalone repair. Sold by Pro Gear and Transmission. Not sure this is the right part for your application? Give us a call.

Permatex 21351 bonds a defogger tab back to the printed heating grid on the rear window. When a tab separates from the grid, the defogger circuit opens and the window stops clearing. This kit restores the electrical connection at that joint. The repair requires no special tools beyond what is included in the kit.
