VersaChem 11109 Rear View Mirror Adhesive

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 itagain and again.Or do like i did, not being able to remove all the parts stuck on the windshield, and having thebase of the mirrior olding thinggy slowly slide sideways and that just isn't right. So having touse a hand scrapper, i finally after almost 20 minutes...i gave the sideways glued base of the mirriorone 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

This would be my third try and getting my rearview mirror to stay on my windshield of my 2012 Altima. Other brands failed within a few days and I received that great gift of arriving at my car to find my rearview handing my the wires for the compass, auto dim, etc. I did a lot of research and did the following on this attempt. 1: Park your car out of direct sunlight in an area that it will remain out of direct sunlight, if you can. Close your windows and run your A/C thru your defrost if it is hot and or humid. Change your A/C to dash vents before you actually apply the adhesive. 2: Clean the metal mirror puck your want to glue on very very vey well. Then, clean it again. 3: Remove any old adhesive from your windshield with a razor scraper or blade, all of it. 4: Take 90% isopropyl alcohol and clean the puck and wind shield area, let it dry and then do it again, let it dry. 5: Use a very light piece of sandpaper on the part of the puck that is going to bond with the window. Rough it up don't remove any more material than possible. 6: Apply the activator to the windows side of the puck only, and give it two applications. Wait for two minutes. 7: Apply a "bean" size amount of the adhesive. 8: be prepared for the puck to slide when you apply it to the window and put pressure on it. Hold it for a minute and let go. 9: Leave it alone for at least one whole day, with the windshield out of the direct sun, do not put your mirror back on the puck till day two. 10: Do not use a reflective sunshade in you front window after your glue the mirror back on. I don't have proof but I think the shade is reflecting the sun and heat back out the windshield and is increasing the temperature of the glass beyond the adhesive limits. I am at two weeks and it is still holding. Good Luck

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.
