Permatex21351 Electrically Conductive Rear Window Defogger Tab Adhesive

17 Jeep Wrangler. One side of the defroster popped off. I used the wipe. I applied more than a drop and put it in a different spot. I then put a clamp on it for 24 hours. It worked. I put the multimeter to it and turned on the defroster and it read 12 volts. It’s been a few days and it’s still holding. We’ll see. The other side that was not glued popped off today so I’ll use it again.

This stuff is amazing and it works. Follow the directions exactly as written and you will have no problem. Well worth the money.

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.

Used car I bought had no rear defrost. Found that one contact came detached and another was half detached. Discovered this from a video tutorial and decided to give it a try. The product is very easy to use, with very clear and straight forward instructions. Only advice is making sure original contact point isn't damaged. If there are breaks in the original mounting area, use 150 grit sandpaper to gently clean off a new area. Simply follow the instructions on the package and you will be good to go in no time.

So let me preface this with, if and when you get it to bond, it works. But I had to buy it twice.My rear window is very sloped. I followed the instructions exactly, held it in place for the specified time, and it fell off. Tried again, it continued to fall off. Gave up as if its supposed to cure within a minute or so and hold the part in place, continuing to try and install it isn't going to help, its too late.I bought ANOTHER package of this, but this time I took some blue painters tape and put it on the back of the tab, I installed it and held it in place, and then pressed the tape in place to hold it, and added some additional tape to support it. 24 hours later removed the tape and voila, it worked. Tested the defogger and it functions properly. Took a star off for this, IMO if you can't use it for 24 hours anyway they may as well have the instructions say the user should provide additional support (tape or otherwise) to hold it in place for a strong bond.Also important to note, the instructions on the package and in this listing say to wipe the activator on both the tab and the window. But there is a graphic on this listing that says not to use the activator on the window. I don't know why that contradictory information is there. I used the activator on both and in my second case when using the tape it worked properly.

My rear window defroster connector was broken off at the base and I was afraid to bring a hot soldering iron to the glass for fear of cracking the glass due to the heat.I carefully followed the instructions that came with the kit and was able to re-attach the broken electrical connector to the defroster.After waiting the requisite time period, I hooked up the wire and tested it: Lo! Rear defrost works again.My wife is happy that I was able to fix her car - therefore I too am happy.

It glued the wires back up… we used a thermal reader and it didn’t show that it warmed up at all. maybe i did something wrong mixing it but hey

This stuff is amazing! Worked fast on my windshield defroster contact. Gave me all I needed for this small repair project! Been 3 months and still holding fast.
