How to Fix a Fallen Rearview Mirror Glass?
2 Answers
If the rearview mirror glass has fallen out, it can be repaired using AB adhesive. Here are the relevant details: 1. Usage Method: At room temperature (25°C), clean the surfaces to be bonded. Then apply Adhesive A and Adhesive B in a visually estimated 1:1 ratio, either by overlapping application or by applying Adhesive A on one surface and Adhesive B on the other, then pressing them together. Perform 2-3 alignment adjustments before fixing for 5-10 minutes. 2. AB Adhesive Function: This adhesive and hardener are mixed in a specific ratio, with the catalyst controlling curing time, and other additives regulating properties such as viscosity, rigidity, flexibility, and adhesion. 3. Storage Method: Prolonged storage in a damp warehouse not only causes the product's humidity to exceed standards but also leads to adhesive failure. This is primarily because the product absorbs moisture, and the adhesive itself has poor water resistance, resulting in softening of the adhesive layer and delamination. For a series of sealing adhesives with certain water resistance, any excess adhesive should be wiped with solvent, and containers should be cleaned with water and solvent for this reason.
That time when the rearview mirror glass fell out of my car, I was really a bit panicked—driving without it is dangerous. I found the glass intact in the garage, but the small clip on the base was broken. My first thought was to stick it back with double-sided tape, but it fell off again after a few days on bumpy roads. After searching online, many car enthusiasts recommended using automotive-specific AB glue or strong adhesive for better results. So, I cleaned the groove and the surface of the glass to remove any grease, applied a layer of adhesive, pressed it firmly for a few hours, and now it’s been holding steady for two years. If the clip is completely broken, buying a new mirror glass isn’t expensive—just a few dozen yuan, and you can find matching models online to replace it yourself. If all else fails, you could replace the entire rearview mirror assembly, though that’s a bit more costly. Remember, as a temporary fix, you can stick on a small mirror for emergencies, but don’t risk driving long distances without a rearview mirror.
