10 Best Rear View Mirror Glue Best 2025 in the United States

The J-B Weld 8276 KwikWeld is a quick-setting, steel-reinforced epoxy known for its strong adhesive strength, boasting a tensile strength of 3127 PSI. This makes it capable of holding parts firmly, which is essential for securely attaching a rear-view mirror. It sets in about 6 minutes and fully cures in 4 to 6 hours, offering a relatively fast bonding time compared to traditional epoxies. Once cured, it can be sanded or drilled if needed and withstands temperatures up to 230°F (110°C), which covers typical conditions inside a vehicle.

This epoxy is versatile, bonding well to metal, plastic, glass, and other surfaces commonly involved in mirror mounting. It is waterproof and resistant to chemicals, adding durability under daily use conditions. As a two-part epoxy, it requires mixing, which can be a little tricky if you’re looking for a very simple, one-step glue. While it handles the heat inside a car, it might not be the best choice if the vehicle is regularly exposed to extreme temperatures above 230°F.

For those needing a fast, reliable, and strong adhesive for rear-view mirror repair or installation, this product is a solid option, especially if you don't mind the small extra step of mixing and allowing curing time.

When it comes to adhesive strength, this product performs well, as it is based on an OEM specified formula, ensuring it meets the rigorous demands of the automotive industry. The curing time may be a consideration, as it takes up to 24 hours for a full cure, which means you'll need to be patient before using the mirror again.

In terms of temperature resistance, the product is quite effective, but the specific limits aren't detailed, which could be a downside for users in extreme climates. It is compatible with glass and metal surfaces, making it versatile for various applications beyond just mirrors. On the downside, some users have reported that the moderate viscosity of the adhesive can sometimes lead to a challenging application if not handled correctly. Additionally, as it is not water-resistant, this may limit its use in particularly humid or wet environments. The Permatex 81840 is a solid choice for anyone needing a dependable rearview mirror adhesive, but it's essential to consider your specific application needs and environmental conditions before making a purchase.

The Loctite 37438 Rearview Mirror Adhesive Kit stands out as a reliable solution for remounting rear-view mirrors securely.

Its compatibility with various materials like glass, ceramic, and metal adds versatility, making it a good choice for different windshield setups.

On the ease of application front, the gel form allows for precise placement, reducing mess and enhancing user control during the bonding process. However, there are a few drawbacks to consider. While the adhesive performs well under various conditions, some users have reported issues with temperature resistance, particularly in extreme weather. Additionally, as it is a gel, it might not be as forgiving if applied improperly, meaning users need to be attentive during application.

This product is particularly beneficial for DIY car enthusiasts or anyone needing a dependable adhesive for rear-view mirror repairs. It strikes a good balance between speed, quality, and ease of use, but users should be mindful of application conditions to ensure optimal performance.
