3M High-Bond Rearview Mirror Adhesive, 08749, 0.02 fl oz, 1 Per Pack

It's been a hot summer and my mirrot fell off. The first time I tried this glue, I followed the instructions exactly. They say to spread the activator, wait a few minutes, and put a drop of glue on the button (and smoosh it around a bit against the windshield). This DID NOT WORK for me. The button fell off the next day (I waited 24 hours) when I tried to attach the mirror. I tried again with the rest of the activator (not much) left in the package, and all the glue left. This time I covered the button in glue. Once again I waited 24 hours. (The instructions didn't say to do this, but I figured I would just to be safe.) Attached the mirror with no problem and it's been a month now and it's going strong. Fingers crossed it continues like that!

Very sticky so be careful getting it only where you want it. Be smart cover your dashboard with cardboard so any drips won't stain it and in case the rearview button you're gluing on falls down. I taped the button to the windshield for a few hours as it dried. In case you mess up the first time like I did you can use a blowtorch or high heat and try to get the button off but it leaves a stain on the windshield

Terrible stuff did not work at all 3M should be Ashamed of this worthless product

Worked just as it said it would. I mixed it according to directions, which were easy to follow. I applied it as per instructions and it has not moved at all. It dried rather fast and was durable before the full curing time, as I was moving the mirror all around and it never gave way, not even the slightest bit. We have had a few hot days already and the heat in the cab did not affect bond at all. Easy to mix once you put the pieces together nothing will leak through the bond. I will absolutely buy this again if I need to fix a rear view mirror, as it met and actually exceeded any and all expectations I had.

I used the 3M Rearview Mirror Adhesive to reattach my mirror, and it did the job perfectly! The adhesive is strong, dries quickly, and is easy to use. It’s a great value for the price. Very impressed with how well it works!

It worked great. Totally easy to use. You have to careful about the directions and read them carefully. I would buy it again.

NEVER IN 80 PLUS YEARS HAVE I HAD ANYTHING FROM 3M THAT DIDNT WORK AS ADVERTISED THIS IS JUST ONE MORE EXAMLE

I have a 2006 BMW (E90) 330xi with a detached rearview mirror. I used several different adhesive products attempting to re-attach the mirror, some specifically designed to re-attach rearview mirrors, some not designed for the task, but designed to attach metal to glass. I purchased 3M High Bond Rearview Mirror Adhesive out of desperation, and just like the other bands that I used previously, I came away disappointed. First, let me say that I followed the directions printed on the package to the letter. I scraped the old glue from the window with a razor blade, used a brand new metal button, thoroughly cleaned the window and button with an alcohol/water solution, used the activator and one drop of adhesive exactly as directed in the instructions. Although, the advertising on the package says cure time is 15 minutes, I waited over 24 hours to attach the mirror. I attached the mirror and the surrounding frame and thought I had finally solved my rearview problem. On Monday morning, I drove my car to work with a fully functioning rearview mirror. During the day, outside temperatures topped 95 degrees, and I'm sure temperatures inside the car were well above 100 degrees, but what I was most disappointed about was that the rearview mirror was hanging by the wiring harness when I returned to the car later that evening. 3M High Bond Rearview Mirror Adhesive bonded the mirror to the window for less than 36 hours. I was about to give up and go to the BMW dealer, where I'm sure they would have wanted the equivalent of my child's 1st semester of college tuition, to re-attach a quarter-sized metal button to glass. I had to try to fix it one more time before resorting to extortion from the dealer. So I went to Auto Zone and purchased Permatex Extreme Rear View Mirror Adhesive. Take note, I did not say Permatex Rear View Mirror Adhesive; there's another word in the title--EXTREME. Needless to say, that product worked, and I can finally use my rearview again like the other 99% of drivers. If you have a heavy mirror, use Permatex Extreme Rear View Mirror Adhesive. It worked for me. ******************************************************************************************************************* - Update 7/23/2021 ******************************************************************************************************************* Disregard all of the glowing remarks I wrote about Permatex Extreme Rear View Mirror Adhesive. The bond lasted for about 72 hours and then fell victim to an extremely hot July day. In an act of desperation, I called the BMW dealer to ask for a price quote to re-attach the mirror, and just as I expected, the quote was exorbitant; coming in at $169 and up. I couldn't stomach dealer pricing, so I called a couple of auto glass repair companies. The first repair shop quoted $50 and he said he would meet me at my residence two days later. He was a no-show. The second repair shop asked me to bring the car to their shop in the early morning before repair techs head out for early morning repairs, and they would fix it for free. I'll update this post after the repair is complete and an observation period of at least 30 days has past. --More to follow. ******************************************************************************************************************* - Final Update 8/22/22 ******************************************************************************************************************* The second repair windshield repair shop managed to glue the mirror holder button back on, but he had to use a lot of glue to get it to stick. And once again, the fix didn’t last long. The mirror stayed on for about a week before it fell victim to a hot day also. However, this time the glue heated the button up so much that it cracked my windshield. The crack starts a the button location and runs right down the middle to the bottom of the windshield. Now I have no choice, I have to replace the windshield. New windshields come with the button already attached.

لا يلصق

A week after using and my mirror is back in place and stable so far. Since it's a one use product I used far more glue than necessary and covered the surface of the mirror holder as I'd read from reviews that following the instructions of "one drop" usually resulted in failure.

What a load of rubbish. Product usage procedure complicated and didn’t hold security camera I was trying to mount. Gave up, threw product away, went to Halfords and brought tube of Evo Stik Performance Technology. This product mounted the camera in 20 minutes.

Perfect adhesive, used as instructed, sticked in an instance with perfectly strong hold. I recommend to follow the instructions as provided in the product.

Great product. Quick, easy and non messy. Great!
