Permatex 21351 Electrically Conductive Rear Window Defogger Tab Adhesive

Let me start with saying that regardless of what are some bad review, it works and it worked very nice for me! Obviously you need to take care of the surface by cleaning it. Follow the simple instructions exactly as they say, and you won’t regret this product! Applied activator after having cleaned surface and the lil connector that need to be stick to rear windshield, let it dry a while (5min), apply conductive glue to part and keep it for a 1min. It worked even though in a vertical position and gravity didn’t bother glue and was perfectly stuck! After 24h it should be fine to use, I personally waited more before using the rear windshield heater. Very nice and good product! Will add some photo, and trust me some idiot before soldered that connector and that’s why it came off and I had to clean the part with a solder to clean it properly from tin soldering residue. Anyway it was easy to use as well and functional, it’s already been 2 weeks and still fine. Will post photos.

Based on feedback I took time to really clean the contact point on the wiring and glass. Followed the instructions with those cleaning instructions, kneeding the material, etc. It is very fluid, I was expecting it to have been a little thicker. No worries, I was able to dab a little on the glass point of contact and then put some on the wiring contact. Not being my first rodeo, I had a small clamp standing by which I gently clamped down until the wiring contact was firmly against the glass but not so much I would risk breaking the contact or the glass. It was mid 70's F and 40% humidity. I left the clamp in place for 7 hours, the glass in the up/open position. After I took the clamp off, the epoxy had a few weeks to cure as the temps were still warm. The first morning I had moisture buildup due to the overnight temps I tested my rear defrost, it worked and I was very happy.... until the next time I tried it. The second time, nothing. It failed. I checked the fuse (it is good) I have voltage running to the contact but nothing is happening. The contact is still firmly epoxied in place, it has not moved and will not move. Something is up with the epoxy that after the first run it seems to no longer be conducting. The TLDR; version: Took excessive steps to prep and install, worked once, now no longer works.

This worked exactly as needed to fix my rear window defogger tab. The repair was straightforward and the adhesive bonded well without any issues. Once it cured, the connection was solid and the defogger started working again like it should. It saved me from having to replace the whole rear glass. Great product for a simple and effective repair. Definitely worth it.

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

One of the tabs pulled off my rear window glass. Dealer said call a glass company. Glass company said we replace glass not repair it. So I went at least a year with no defroster. I decided to try this even with lack-luster reviews. I filed the tab flat, prepped it as the instructions said, found a good spot and stuck it on. I was pleasantly surprised that it worked perfectly. I got my defrosters back.

Followed instructions very carefully. Lasted about a month and that was it

Some reviews of this product claim it does not stick, it sticks really well so I can only imagine they have no experience with this type of glue and missed one of the instructions steps. The instructions are pretty clear but both surfaces must be very clean, dry, have no loose bits to start with. You may need to very lightly sand both sides. The side on the glass needs to extremely gently sanded/cleaned because you could easily remove the metal from the glass. Make sure you wait for the preparation wipe to dry (5 minutes) and make sure you have fully kneaded the glue inside the pouch. You need to press the tab onto the glass for a full minute. You cannot perform the gluing if the temperature is too cold or too warm. Follow all of the directions and this is a great product.
