The Permatex 49450-6PK Super Glue is a versatile adhesive that comes in a pack of six 1-ounce tubes, intended for various materials such as metal, plastics, rubber, vinyl, paper, wood, textiles, and cork gaskets. This super glue is formulated for a fast, long-lasting bond and is ideal for automotive applications like trim, logos, knobs, and minor interior repairs. With a transparent finish, it ensures a neat application by filling gaps up to .004 inches.

One of its standout features is its ease of application, allowing precise placement where needed without much hassle. Additionally, its compatibility with multiple materials makes it a handy adhesive for various repair and carpentry tasks. When considering its use specifically for rear-view mirror gluing, one might need to ensure it meets the required temperature resistance and curing specifications.

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.

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.
