You should not forget the rearview mirror in your vehicle, as you should be using it whenever you drive. In older vehicles, the rearview mirror is usually mounted on a pedestal that hung from a mounting point just above the windshield and is held in place by two or three screws.
Newer vehicles usually mount the rearview mirror on a bracket glued to the inside of the windshield. Both outside and inside rearview mirrors can be damaged in collisions. The inside mirrors are usually attached to the windshield glass using a quick bond adhesive.
Apart from collision damages, inside rearview mirrors are prone to get knocked from the windscreen, especially if your car is quite old and the mirror has been in place for some time. Refitting an interior mirror is not a difficult job, all you need is the best rearview mirror glue.

What Kind of Glue Do You Use for a Rear View Mirror?
There are various bonding agents that you can think of. In my experience, rearview mirror adhesive outshines most super glue type bonding ingredients. The best and most effective are rearview mirror glue products, such as the 3M High Bond Rear View Mirror Adhesive.
Rearview mirror glue does permanently bond the brackets of a rearview mirror to the windshield in a matter of seconds. The effectiveness of this kind of product does not end there; most rearview mirror glues can be used to bond glass to glass and metal to metal.
Refitting a Rear View Mirror with the Best Rear View Mirror Glue
As I mentioned earlier, repairing a rear view mirror does not have to be a difficult proposition. In fact, you won’t need any special tools to do it. For the best chance of a long-term repair, you need high-quality rearview mirror glue and guidance.
You can find a well-equipped rear view mirror glue kit from your local car parts shop, but make sure the kit is up to date and from a reputable brand.
Separating the Mirror
Your rearview mirror comprises two parts that are connected through a ball joint. One part houses the mirror glass, and the other part attaches to the windscreen (the mirror base).
The first thing to do is separate the two parts; otherwise, the mirror will be too heavy and will fall off before the adhesive has had the chance to work. The two parts are normally a few inches apart and press back together with a little effort.
Repair the Mirror Base
You should follow the manufacturer’s instructions exactly, although the following is a brief guide:
Sand the mirror base and the windscreen button (metal disc on the windscreen), so that they are completely smooth. Rough surfaces will prevent the glue from making a strong bond.
Once both surfaces are completely smooth, remove any dust and dirt from both sides.
Apply the best rearview mirror adhesive to one or both surfaces, according to the manufacturer’s instructions. Press the two parts together and hold them in place.
Hold the mirror base to the windscreen button (metal disc on the windscreen) for as long as the instructions say to do. Allow the rearview mirror glue to settle overnight before refitting the mirror.
Refitting the Mirror
After allowing sufficient time for the glue to set, you can refit the mirror to the base, which is now glued to the windscreen. Be careful not to break off the mirror base from the windscreen. Try holding the base in one hand whilst pressing the mirror with the other.

Factors to Consider Before Buying a Rear View Mirror Adhesive
The choice of the best rearview mirror glue is huge in the market, and not everyone can make the best buying decision. Apart from the above-reviewed products, I have prepared a list of the most important factors to consider before buying a rearview mirror adhesive.
When working on your vehicle’s rearview mirror, you need to choose a rearview mirror glue kit that will produce excellent results. This is to ensure that the glue will hold properly for safety reasons, and the results appear professional.
Therefore, choose a high-quality adhesive that is capable of bonding metal to glass. Such a product is perfect for refitting a rearview mirror to a windscreen. Top quality glue should be easy to clean and use, and it should bond in a few moments to give the best results.
You should always ask yourself the following question, “How long does rear view mirror glue take to dry?” The best products should take a maximum of 24 hours to produce excellent bonding results. Do not settle for a model that will take a significant amount of time to dry.
You can also make use of a hairdryer to speed up the drying process. Personally, I prefer using high-end models that have a good reputation for quick drying. Personally, I recommend an adhesive that has a 10-second handling strength, 2 minutes full strength, and 24-hour full cure.
Rear View Mirror Glue Temperature
You need to buy a rearview mirror glue kit that has excellent low-temperature curing. It should also be flexible with outstanding resistance to thermal cycling. In my experience, the ideal product is one that has a working temperature range of -130 to 230 degrees Fahrenheit.
The best rearview mirror adhesive must be heat resistant. This is so, since the windscreen of your car may be exposed to direct sunlight for extended durations of time when driving or parking. Therefore, if the adhesive is not heat resistant, then the glue may loosen up, detaching the mirror.
There are other factors that the bonding glue will be exposed to, including vibrations due to bumpy or rough roads; accidental knocking by you; and humidity due to rain or moisture. So, only glue with excellent resistivity will be able to withstand all the aforementioned factors.
Rear View Mirror Glue Comparisons
Mirror Glue vs. Super Glue
There shouldn’t be any debate about the two products, really. Rearview mirror glue is a structural acrylic system that is designed to skillfully mount rearview mirrors to the windscreen, and it is resistant to heat, impact, vibration, chemicals, and moisture.
On the other hand, super glue is primarily made of cyanoacrylates. Cyanoacrylates are fast acting, which is basically instant glues. However, the cyanoacrylates do not have the excellent properties of mirror glue, such as resistance to heat, moisture, chemicals, vibration, or impact.
You should not dare to use super glue on your windscreen. This product can potentially crack your windscreen. It is fast acting, but it does produce too much heat in the process that can lead to cracking. Superglue will also succumb to humidity, moisture, and vibrations.
