What kind of glue should be used to reattach a fallen car rearview mirror?

You can use mirror base adhesive, which is a specialized glue for car glass rearview mirrors, similar to AB glue. Car rearview mirrors are located on both sides of the front of the car and inside the front of the vehicle. They reflect the situation behind, beside, and below the car, serving as the "second pair of eyes" and expanding the driver's field of vision. More relevant information is as follows: 1. If you can't manage to stick it back no matter what, you can use a suction cup rearview mirror. This type of rearview mirror doesn't require adhesive on the back; it only needs the suction cup to adhere to the glass, making it very practical and convenient. If you purchase a heavy-duty suction cup, any dashcam can be hung on it. 2. Generally, factory-installed rearview mirrors won't fall off under normal use unless heavy objects are hung on them, such as some pendants or dashcams attached to the rearview mirror. When reattaching, be sure to remove these items, and it's best to find a way not to place them on the rearview mirror.
I've repaired many cases of fallen car mirrors. A detached rearview mirror is no small issue—never use ordinary all-purpose glue haphazardly. The best solution is professional automotive structural adhesive, such as 3M double-sided tape or epoxy resin glue. These materials are heat-resistant and vibration-proof, whereas regular double-sided tape won't hold firmly and may detach again after a few days of driving. During the repair, first clean the mirror base and car body surface thoroughly with alcohol to remove residual glue and grease. Then apply the adhesive or tape evenly, press firmly, and wait at least 30 minutes for the glue to cure. Safety first: Without a rearview mirror, the risks of reversing and lane changing increase significantly. After reattaching, drive slowly to a professional repair shop for inspection as an extra precaution. For routine maintenance, regularly check for tape aging and replace it periodically to prevent accidents.
My car's rearview mirror fell off last week, and I panicked at the time. I used regular double-sided tape from the supermarket, but it loosened and fell off after just a few days, almost causing an accident. Later, a friend recommended 3M automotive-grade heavy-duty tape, which holds much more securely. When cleaning, I thoroughly wiped the base with alcohol pads to ensure it was free of dust and grease before firmly attaching it. After sticking it on, don't rush to hit the road—wait for the adhesive to dry completely before moving. Safe driving is no joke. Driving without a mirror is extremely dangerous due to large blind spots; it's best to temporarily reattach it and head straight to a repair shop for professional reinforcement. Personal lesson: Regularly check the condition of the adhesive strips, and replace them if they become aged or hardened to avoid emergencies on the road.
