10 Best Rear View Mirror Glue Best 2026 in the United States

The Permatex 81840 Extreme Rearview Mirror Adhesive Kit is designed specifically for securely mounting rearview mirrors to windshields. It uses a two-part system including a small adhesive vial and a medical-grade activator towelette, which helps control mess and improve accuracy during application. This kit offers professional-strength adhesive that matches original equipment manufacturer (OEM) standards, ensuring a strong and reliable bond.

Its medium viscosity makes it easier to handle without dripping, and the silicone-based formula is waterproof, providing good resistance against moisture. The adhesive is compatible with most automotive glass surfaces, making it a versatile choice. The small volume of adhesive included (.01 oz) is sufficient for typical mirror mounting but may require careful application to avoid waste. Silicone adhesives generally handle a range of temperatures well, making them suitable for everyday driving conditions.

This kit is a solid option for anyone needing a reliable and professional rearview mirror adhesive without complicated steps. It is especially useful for DIY repairs or quick replacements.

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.

The Permatex 81840 Extreme Rearview Mirror Adhesive Kit offers a reliable solution for securely attaching rearview mirrors to windshields. Its two-part system, consisting of a cyanoacrylate adhesive and an activator towelette, is designed for professional strength applications, which makes it suitable for both DIY enthusiasts and professionals. Users appreciate the medical-grade towelette that enhances application accuracy and minimizes mess, a definite plus for those who might not be very experienced with adhesive products.

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.
