Permatex 21351 Electrically Conductive Rear Window Defogger Tab Adhesive

Lately my old civic’s rear defogger tab kept popping off, which is fun when you’re driving home at 7am after a twelve hour night shift and the window’s fogged. I grabbed this stuff hoping to squeeze a bit more life out of the car instead of paying a shop. Cleaned the glass, cleaned the metal tab, pressed them together with tape, then let it sit while i tried to stay awake with cereal on the couch. Peeled the tape, snapped the connector back on, and it actually works again. I could see clearly backing out of the hospital parking lot, so I was pretty glad. Tiny tube, but for me it fixed that one annoying thing.

Whether facing extreme temperatures, moisture, or vibrations, I have full confidence that the bond will remain intact, providing long-lasting performance. Additionally, I appreciated the versatility of this adhesive.

The Instructions say to clean the Tab and a fresh area of the Window Defroster Grid, I scraped and sanded the tab to a bright metal surface. I lightly sanded a nearby area of the Window Defroster Grid. The Instructions say to knead the packet for 1 Minute to distribute the conductive particles within the adhesive liquid. I mixed it for 2 minutes to get an even looking mixture. The Instructions say to hold the metal tab in place for 1 minute to let the glue setup. I held the tab in place for 5 Minutes. The Instructions says to wait 24 hours before connecting the wiring and powering the Defroster. I waited a week for the repair to fully cure the adhesive. The connection felt solid and showed 0 Ohms resistance. On the next frosty morning; the defroster worked great. I powered it off within 5 minutes and the window was clear. (I didn't want to have the defroster running until timeout if it was not necessary.) That was the last time the Defroster worked. Upon further inspection; the metal tab is still solidly attached to the window; but there is 12+ Ohms resistance. Voltage was OK at the terminals and I noticed a spark as the meter probe brushed between the metal terminal and the Defroster foil on the Window. Power no longer passes between the Defroster Terminal and the Grid. Save your Time and Money from this product and spend it on a proper solder repair.

Where this helped was fixing the loose rear defroster tab on my old sedan. I sanded both contacts, used the little wipe, mixed the liquid till it turned brown, then held the tab on the glass for a couple minutes. Waiting 48 hours felt too long, and one corner still looks messy, but the defroster works again and im glad.

expensive, took a long time to dry, does not seem like it worked. instructions were clear. unknown how long it will last.

It actually works I seen lots of reviews on this people saying it dont work I decided to try it and it works What I end up doing is sanding the contacts of the defroster terminal that came off the window and on the window it self and clean the contacts where it was mounted on the windshield then use the wipe it give you the activator wipe the contacts and the part on the glass wait 1 min while your doing that mix the solvent until it get like a brownish color then put a couple drops of the on the contacts and hold it onto the window for 2 min or so then let it cure 24 to 48 hours then you can use your back defrost again.

Followed the instructions and the tab is very secure. Tested the heating element and it is working. I would bet that negative reviews are coming from people THAT DID NOT FOLLOW THE INSTRUCTIONS. BETCHA!! Will see if this fix lasts......for now it is solid.

Meticulously followed the instructions, waited 2 days just for good measure, tab still came off. This is garbage, don't waste your money, this is $15 garbage.
