I came to my car and my mirror was hanging by the wire. I think the sun melted the adhesive off due to no signs of forced entry. Can I use crazy glue to put it back on?

Use super glue (CA). It'll hold for a long time if you don't strike the mirror with any hard objects.

Suoer glue should work. Thats actually a pretty common thing to happen in older cars in warm climates,

better than superglue - use 'rearview mirror adhesive'.

(I'm not sure it's any different from superglue, seems like the same stuff... but I'm no chemist)

"rearview mirror adhesive" if I remember right is a clear epoxy. I'd use it instead of superglue. Superglue is a cyanoacrylate that will degrade more quickly under UV (sunlight) than the epoxy, I am told.

where do i find this magical adhesive?

rear view mirror adhesive (the clear stuff) is available at an auto parts store - NAPA, AutoZone, CarQuest - and also available (usually) at GM dealers (I don't remember the P/N).

that specific adhesive works much better than any "superglue". my dad used to have a problem with his mirror falling off b/c he wasnt careful when removing the sunshade on really hot FL days. he tried all kinds of cheap glues, but eventually bought the stuff made to hold rearview mirrors up and it had held ever since. i even had to use the stuff on my Riv about 3 years ago b/c one hot summer day i had the same thing happen to me (found it hanging by the wires), but after re-gluing it, it has been fine ever since...even with 2 kicker solo's in the trunk constantly rattling it

Super glue and the special rear-view mirror adhesives are both types of CA (cyanoacrylate). The specific rear-view stuff may be a better formula for the job. I used a type called CA+, available at hobby stores for model building. It's been holding now for over 2 years.

The key really isn't the adhesive, imo. It's preparation. use a razor blade to scrape off the old glue, and alcohol to clean the metal and glass surfaces. Use enough glue to coat the metal part on the mirror.

I can say that quick-drying epoxy didn't work for me. The heat of the window cured the epoxy before I could get it to stick! The CA or mirror adhesive seems to be the best choice.

prep is equally important with these fixes. IDK how it is everywhere else, but down here, during hot summer months, napa /AZ /etc. has the rearview adhesives on the front desk, right next to the cans of freon
...at least it will only be 95* today b/c of constant rain and clouds

Aaron: Some clear epoxy does not dry quickly, some does. With 2-part, depends on temp and on how much hardener you mix in - not enough and it never dries, too much and it dries too fast and gets tough to work, may get brittle.

Just the same, thanks for the correction about the mirror adhesive - apparently there are different kinds available. the CA would keep on the shelf longer than the 1-part clear epoxy.

Finally -you are ABSOLUTELY right about getting the window clean before cementing on the mirror. I keep a couple bottles of dry gas (the really cheap wood alcohol stuff, with no additives) around for just this sort of cleaning. 91% isopropyl (Wal-Mart, CVS has) works OK, I think dry gas is better. ALso - be careful to be sure the towel or cloth is clean and does not have any residue - not even fabric softener. FOr something like this I'd probably use a paper napkin.

I realize this is an old post but has anyone dealt with re-glueing the rearview mirror back on?

The massive heatwave a couple weeks ago dropped my mirror and i have made several attempts to get it back on but it just fell off again...

I took the little wedge out and glued it separate from the actual mirror then it broke off when i was reinstalling it... the clip is designed for a 200 pound mirror. So I tried the duct tape and epoxy method which held for 5 days.... now I'm looking for a writeup
