VersaChem 11109 Rear View Mirror Adhesive

I was skeptical about this glue. Some reviewers said it doesn't work. I give it a try because it was cheap. I applied it on for a month now and no problem so far. I don't know why people give it a bad review. I follow the direction and it sticks. There are a few things that I have to assume that wasn't clear in the instruction. 1. Applied prime to surface. It wasn't clear to apply only on the metal piece of the mirror or both mirror and windshield. I applied on both. Also instruction said let the prime dry, but how long. I let it dry for 5 minutes to make sure, but you can't tell by looking at it. And I don't want to touch it. 2. Instruction said to hold it with pressure for 30 seconds for it to stick to the windshield. I have to assume they are talking about the metal and plastic piece that holds the mirror and not the whole mirror itself. Commonsense said it will be too heavy with the mirror. I hold it for 1 minute and it was slippery. It try to move around. Instruction said not to move it around when applying glue. After it hold up, I left it there overnight before adding the mirror. It was hard as a rock. 3. Instruction didn't state what temperature it needs to be for optimal performance. I assume it can't be too hot or cold. So I applied it at room temperature and it worked perfectly for me. Overall, this product worked as advertised.

Excellent product, worked great, first time using anything like this before. I scraped all the old glue off the button and window first. I used a fine grade sanding block (used for sheet rock) on the button to clean any excess glue off and to rough it up a bit. I then cleaned off the button and the install spot on the windshield with alcohol. I let them dry for a minute then applied the activator on the button and let that dry for 2 minutes. After that I put a drop of adhesive on the button. I lined the button up to where it goes on the windshield and firmly pressed on it for 2 minutes. The directions say it is good after 30 minutes but I let it sit overnight to be on the safe side. It seems to be holding very strong as I had to bang a little bit on my mirror to get it on since my mirror has a large tension clip that goes over top the entire button. I am very impressed with the product so far. I thought I would have trouble with it reading all the reviews on other products, that is why I got this one since it had the best reviews. The few that are having trouble with this product must not be doing the prep work/cleaning properly or maybe they have an expired product.

UPDATE: 5 YEARS LATER (2023) the mirror is still holding strong, thru many furnace Texas summers!! After spending a few hours weeding through reviews, this is the product I came up with. I've been trying to replace the mirror in a 2003 MDX. No black paint area to stick to and what seems to be the slipperiest windshield glass ever. Prior to each attempt, I carefully cleaned the windshield with a razor blade and Windex (never use a razor blade on dry glass), followed by alcohol with a clean paper towel. The glass was visibly clean with no signs of dirt/oil. I first tried the Permatex Extra strength, following their directions exactly. When putting the mirror back on long after the recommended drying period, the button popped off the windshield the first time I tried to adjust the mirror position. Second, I tried the regular Permatex product, followed the instructions, waited even longer before mounting the mirror only for it to pop off (button from windshield) upon first adjustment. Tried silicon caulk, waited days, and the button appeared to be firmly attached to the windshield this time but alas, first adjustment attempt popped the button right off the windshield. In all three attempts, the adhesive (and caulk) was stuck very firmly to the metal button and the failure was always between the adhesive and the windshield. After each attempt, I filed the old adhesive off the button with a flat metal file to ensure it was fully removed and to add a tooth for the next attempt. Finally, I tried this product. This one said to prime only the button, not the windshield (Permatex products say to prime both the button and windshield). This may have been the difference since the primer always seemed to leave a greasy film on the windshield. Either way, as soon as I stuck the button with the adhesive on it to the windshield, I could tell this was a better adhesive as it stuck firmly, immediately. I waited a couple days to put the mirror on (~50 degree weather) but once on, it's still on a month later. Even though it's holding fine, from the outside, I could tell I got little more than 50% coverage of adhesive on the surface of the button. The directions say to use one drop or a small bead. I ran a small bead the length of the button but it wasn't enough to get full coverage and likely the size drop I would have used would have been less, based on my experience with the thinner Permatex liquids. So, my recommendation is use a little more than you think you should. I believe any extra that you apply would squeeze out the sides. Again, mine's stuck on with half coverage.

Whatever you do, don't waste your money on this product, it does NOT work! On sunday I glued my rearview mirror on. I applied the primer, let it dry for 1 minute, applied the glue and put the small plate on mashing hard on it for 1 minute...JUST LIKE THE DIRECTIONS SAID TO!!! I did not attach the mirror yet because I wanted it to set over night before putting the mirror on the little plate on the windshield. Monday I went out there and checked to see if it was going to hold. It felt pretty strong as I tapped on it, so I assumed it would hold. I then attached the mirror on the plate...notice I let it set over night before putting the mirror on the plate. Today is tuesday and I went around the corner store within 3 miles of where I live and the whole mirror fell completely off! It fell to the floor board and as I looked at it laying there, I thought: "Well THAT was a waste of my money!!!" Moral of this story: DON'T WASTE YOUR MONEY ON THIS PRODUCT, IT DOESN'T WORK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I had mixed reviews on this one. I remember buying a product that was similar or maybe this same one in the past and it worked really good so I bought this and it didn't work at all even though I read and followed the instructions. I bought another one though and followed the instructions again and am mystified as to why it worked so well the second time. So I give it 4 stars since it has worked so well the second time and am so happy that the mirror is not falling off in the heat of the summer. I just thought of a reason, the second time I used a brand new metal plate that gets glued to the window and attaches to the mirror. Maybe that was the difference.

tHiS is a ONE time try to get that darn rear view mirror to stick to the windshield. If you do not prepare the windshield perfectly, you may want to plan on cleaning it again and again. Or do like i did, not being able to remove all the parts stuck on the windshield, and having the base of the mirrior olding thinggy slowly slide sideways and that just isn't right. So having to use a hand scrapper, i finally after almost 20 minutes...i gave the sideways glued base of the mirrior one more strong scrapping, and CRACK the entire windshield blew into the most pretty spider web like cracks all over the place. I hung my head in defeat...and maybe cried a bit...."don't tell anyone, because big ole grown men don't cry i was told". Well at least don't let anyone see you crying. If i cry...just because i'm crying... it makes me cry even harder...because to me that shows Defeat! So i sucked in the snot that was in my nose...wiped my tears away, and by just moving my eyes i looked right then left , just to see if anyone had seen me crying...and no, no one around. After driving in shame to the onlookers..because I just knew every living soul on earth was looking at my car windshield, probabibaly er possibly or probibale thinking i can't spell, and they are right...but nonetheless or none-the-less, I purchased a new windshield for about 236.99 for a 3 dollar fix. I always say: "If it ain't wrong, then it ain't right". That means to me at least, expect the worst thing to happen, and it will, even after the "broken" thing is to be fixed, it will break more. With the windshield purchase.. the ticket for not having a rear view mirror, and the glue kit, I'd say after all is done and said. . .the 453.09 dollar fix for a broken mirror attachment wasn't all that bad to be expected.. I just hope my next project isn't too much more than that. Thank YOu

Rear view mirror would not remain in place until we used this glue. The mirror has not come lose since using this adhesive.

Every rear view mirror adhesive has negative review, but as long as the installation is done correctly, they should hold. Here's what I did: ORIGINAL BUTTON REMOVAL: Watch youtube for guidance. I took my Porta-Sol's micro torch and heated the original button until the adhesive let go of the button. As long as the flame does not touch the glass part, it should not crack. Lightly wiggle the button with a pair of pliers with twisting motion (NEVER force it to remove or the windshield will crack). On the new metal button that sticks to the windshield, I cleaned the windshield with alcohol and wiped with dry paper towel. I then lightly sanded the sticking surface of the metal button with 80-grit sandpaper to leave some scratches. Again, I cleaned the metal button with alcohol & wiped with dry paper towel. Then, I applied the primer onto the button with two overlapping paths; two layers of thin films. Let it dry for 2 minutes (the direction says 1-2 minutes). Then, I started the engine and turned the air-conditioning on to keep moisture away (even your fingers produce enough moisture via perspiration that would affect the adhesive). I then applied a thin bead of adhesive onto the button and very carefully aimed at the mounting position marked with masking tape, put the button against the windshield and held firmly for 1.5 minutes while the air-conditioning was still running. I then let it sit overnight and now the button is rock-solid.

Did a really great job of reattaching the review in my ML350. Alternative is to replace the whole windscreen at considerable cost. Arrived quickly and was easy to use.

It's been holding the after market mirror on for about 6 months now. Now problems!

Followed instructions and attached mirror mount in 10 mins . So far it’s still attached to windscreen

very good product if you follow the instruction it will work perfectly, used it for about 2 months no issue so far

Tried everything to stick my rear view mirror on except pay £100 from a garage to do it, this done the trick
