Permatex 81844 Professional Strength Rearview Mirror Adhesive, 0.02 Fl Oz

Works well. Still holding my mirror up numerous months in. Usually the mirror falls off after 12-18 months, so I get another pack of this to put it up. Application isn't simple-sweet, but it's not hard either. You have have to dedicate a solid five to ten minutes, clean the glass well, hold the mirror in place for a few minutes until it dries (awkward, but shoulder-strengthening). A good product, recommended.

I normal wait a little while before I write my product reviews just to make sure the product doesn't break or disappoint after a week...However, this product works just as fast as it took to open the packet and read the instructions. I don't know what type of chemical adhesive reaction is created after this product touched the glass but I could tell INSTANTLY that the permatex was working and this was the correct purchase option. I even dropped the metal hanger and the oil adhesive did not stick to me or my clothing. It wiped right off. But when I re-applied it and placed it on the activated area of the windshield glass it bonded immediately. Incredible! I naively tried to hang my mirror with other adhesives first which all failed, and I wish I would have just used permatex to begin with. Still its done and I'm more than happy with the results. Best $4 I've ever spent lol!

Product never properly cured, around 3.5 hours after application I went to check and was able to remove the puck by hand. There was essentially zero adhesion to the aluminum puck and a large spot was still liquid on the windshield. While I could have gotten a bad batch, I think the applicator wipe is just not a consistent way to mix in the activator with the resin. I wouldn't waste my time on this which does mean you will need to buy 50-100x the amount of epoxy you need for a job like this and let it you in your garage. Time is money and with the amount of time I've now wasted, Permatex is permanently off my list.

The mirror on my 93' Nissan 240SX fell off due to old age and from me stuffing a plushie between it and the windshield. Followed the instructions to a T and it worked out. It feels solid on the windshield. I've read a dozen of the reviews saying it's garbage and doesn't work or hold up for long. I'll try to update this review if I can. So far I've had it on for one month. For installation, I was on the colder end of the recommended temperature so I preheated the windshield with a heat gun for about 3 minutes. Just warm to the touch. Nothing crazy. And after applying the metal nub to the windshield I periodically warmed up both sides of the windshield so the temperature would cool down slowly. The key is to remember this product works because it's a chemical reaction and you sort of have to make it an "ideal" place for the reaction to happen. If this product doesn't work out for you, there are suction cup mirrors that look the part and are around $15. Thanks for the read. Update: 5/20/2025 It fell off after being exposed to the sun on a 95+ degree day. I did hit it with my head really hard once a couple of months ago so maybe that's what caused the glue to weaken. Up until this point there was absolutely zero wobbling. I'd still probably recommend this product and try it again if I had more.

I do not have a garage so the rear-view mirror is almost always facing the sun in the daytime. In the Summer the metal will get too hot to touch but this adhesive has lasted 5-7 years in the past. Critical step is to make sure both surfaces are clean, and make sure the surface of the mirror mount is flat and clean. I use a medium and fine grade of sandpaper on a hard flat surface; simply sand the mirror mount surface and rotate it as you sand it. It will be better than it was at a minimum. Then follow directions for the product and wait 24 hours if possible before installing the mirror weight onto the mount.

This is the third time I have had to reglue the mirror. This is the 2nd time buying this product. It is easy enough to use and it does work for some time. This time I was extra careful to sand the metal button and clean it after. Let's see how long it lasts this time.

The advertisement is accurate. I like this Mirror Glue Kit, You get everything you need including GREAT Instructions on how to get the Job Done. Very satisfied.

I was hoping for five stars coming from a name brand as in this company. However, the product failed to hold and my mirror fell off again. I did all it said in the instructions too. I even tried 3M and lasted a little bit longer then came off as well. Got to find out what my cars manufacturer uses, hopefully then it will stay put for good.

Worked exactly as described , just a quick clean of the window and button , a big drop of the glue hold it in place a min , left it alone n hour then my mirror went back into place strong and secure

Worked well for glueing metal to glass

No lo recomiendo, seguí las instrucciones y solo duró un día

Product is great but price is too high. Otherwise Satisfied.
