81840 Extreme Rearview Mirror Profressional Strength Adhesive Kit, single unit

Starting with just a small drop in the center worked nicely. After letting it cure for several hours, the button stayed in place. I eventually bought a new mirror because the edges of the old one were getting worn down. When I attached the new mirror to the button, it popped off with minimal adjustment. Glad it was easy to use, but I might need a stronger adhesive next time.

Purchased this to reaffix rear view mirror. Removed all adhesive from the button and the windshield, and I'm not talking most of it, you have to remove all on both to for the best results. I used nail polish remover to remove the adhesive. First time I put 'a drop' in the center. I let the button cure for 8 hours later and it stated up. Ended up purchasing a new mirror because the edges of the existing were starting to deteriorate. When I installed the new mirror on the button, it came off when I adjusted the mirror. So I thought, the instructions read 'use one drop' however not how big of a drop. I had another adhesive kit and went for round 2. I made the biggest drop I could in the center and put it up. An AI result suggested letting it cure for 24 hrs and I did so with it parked in a garage because of the 30F temps. Put the new mirror back up 24 hr later and was able to move adjust it without issue. We'll see how long it lasts however do be sure you follow the instructios and be sure your bonding surfaces are clean as new. Good luck...

Thoroughly cleaned windshield and button, used the primer and adhesive as directed, all seemed fine. Mirror fell off three days later.

I recently used the Permatex 81840 glue kit to fix my rearview mirror. it works well and feels sturdy once applied. perfect for those small repairs in the car. appreciated how easy it was to use during a quick fix at home 🚗. glad it held up so far.

This item is made well and comes with clear instructions. It has been very helpful during my use at work. I'm glad I chose this product.

First, let me say this; The car I've used this on twice is a 1994 Thunderbird LX. The rear view mirror is self dimming and heavier than the average mirror. The first time my mirror dropped, I purchased this product, followed the directions and rehung the mirror. About 2 years later my mirror dropped again. So, I purchased this product and did the above again. HOWEVER... This time I screwed up. I glued the windshield mount on upside down without realizing it and let the adhesive set. OOOPS... Thank god for the internet as I watched a few video's that showed that most adhesives could be loosened by using heat. For me, cold weather had set in right after I screwed up. So, I had to do this gradually with a hair dryer, then a heat gun so I wouldn't crack the windshield. Luckily the windshield didn't crack, the mount came off and I was able to easily remove the adhesive from the glass and mount. I drove the car with the side view mirrors until it warmed up and I was able to reinstall the rear view...right side up. It's been around 2 years and still holding. We'll see if it drops again. Will I use this product again? Yes. I screwed up and was easily able to fix my mistake without going to a shop. If I have to go through this every few years, I already learned and know the routine. Suggestion for you... Before you clean your old adhesive off of your windshield, use a marker on the outside to show where the mount was. You will be able to see this outline from the inside to make sure you're position is correct as well as avoid installing the mount upside down. The marker will come off the outside easily with glass cleaner and a little steel wool/scotch brite. Overall, 5 stars for saving my butt when I messed up. 4 stars because I have had to go through this every few years. It could be the weight of my mirror, the adhesive, or something I don't realize I'm doing wrong. Either way, it does the job and has your back if you screw up.

Overall, this has held up nicely during my garage repairs, and I’m happy with how effectively it works. It’s a helpful item to have on hand for various tasks around the house or in the garage.

I bought this Loctite Rear View Mirror specific glue and it FAILED in 5 days. Mirror fell off. It was not my first Rodeo, so everything was done correctly. Bond was just no good in Florida Heat. To add injury to FAILURE...just a day before it fell off I noticed a 1 inch crack going left and right from center of the Metal tab on windshield. (It's grown to 3 inches but seems to have stopped now. Can't be felt on either side of windshield with fingernail or Razor Blade, so it's not to the exterior.....YET.) I used just ONE DROP in center and pressed it up to the glass and held it in place for proper amount of time. NO crack seen the next day when I put the mirror on. The "Activator" reaction with the glue must have had some serious heat that I didn't notice on my Thumb while holding it. I tried the Loctite cheaper Glass Glue as well since it is rated to 176F and I've measured temps of over 140F on my Truck windshield. It failed within hours of mounting mirror after letting tab cure for 48 hours. I'm trying the Loctite 5 Minute Epoxy now. It's only rated to 120F so I'm not hopeful...but it's still on after two days now. LOL If this fails....I will use PERMATEX 5 Minute Epoxy that I have used on my Golf Clubs for Decades. I've NEVER had a bond fail on those clubs. Need the Heat Gun to change out shafts. P.S. I saw Ole' Scotty Kilmer using this stuff on YouTube and poo pooing people who say it fails...Pfftt...rofl :~)

Following the manual and waiting for dry periods of eqch steps,the outcome is great.My mirror in a Chevy Astro van is heavy.The weather....well..Dubai! 42C normally.So...the challenge is on.As the first day,I can say it is snug.After few moments of putting the metal button with the mirror on,I couldn t move it anymore.Left for overnight with some tape on it to release the weight a bit.Today I tested.Boy....it s not going to come off easily.
