1. Gorilla Heavy Duty Mounting Tape: Best Overall
Gorilla Heavy Duty Mounting Tape is a double-sided tape that provides an immediate, strong bond without the mess of liquid adhesives. Based on our research, it holds up to 30 pounds per square inch, which is sufficient for most standard rear view mirrors. The tape is weather resistant and works on glass, metal, and plastic, making it a versatile choice. Owner feedback consistently praises its ease of use and reliability for mirror reattachment.
However, this tape may not be ideal for very heavy mirrors or vehicles that experience severe vibrations, such as off-road trucks. Some users report that the bond can weaken over time in extreme heat. If you need a permanent solution for a heavy mirror, consider a liquid adhesive instead.
- Holds up to 30 pounds per square inch, suitable for most rear view mirrors
- Works on glass, metal, and plastic surfaces
- Weather resistant: withstands heat, cold, and moisture
Pros: Incredibly strong immediate bond; Easy to cut and apply, no curing time
Cons: Not suitable for extremely heavy or vibrating mirrors
2. Permatex 81850 Rear View Mirror Adhesive: Best Liquid Adhesive
Permatex 81850 is a liquid adhesive engineered specifically for rear view mirrors. According to the spec sheet, it sets in 10 minutes and reaches full strength after 24 hours, creating a permanent bond that can withstand extreme temperatures from -40 to 300 degrees Fahrenheit. Owner reviews highlight its strong hold on glass and metal, making it a favorite among DIYers who want a factory-like fix.
The main drawback is the application process: you must clean the surface thoroughly, apply the adhesive to the mirror button, and hold it in place for 10 minutes. This can be tricky and messy. If you prefer a no-fuss, instant solution, a mounting tape might be easier. Also, once applied, removal is difficult without damaging the windshield.
- Specifically formulated for rear view mirror attachment
- Cures in 10 minutes, full strength in 24 hours
- Works on glass and metal, temperature range -40 to 300 degrees F
Pros: Designed specifically for mirrors; Excellent heat and cold resistance
Cons: Requires careful application and curing time; Messy if not applied precisely
3. 3M 03601 Scotch-Weld Plastic & Rubber Instant Adhesive: Best for Plastic Buttons
3M 03601 is a cyanoacrylate (super glue) adhesive that excels at bonding plastic mirror buttons to glass. Our research shows it forms a strong bond in seconds, which is convenient for quick repairs. The formula is gap-filling and resistant to moisture, making it suitable for automotive environments. Many owners report success with plastic buttons that have separated from the mirror.
However, this adhesive is not intended for direct glass-to-glass bonding, so it won’t work if the mirror itself is broken. It can also become brittle over time if the vehicle is subjected to constant vibration. If your mirror button is metal or you have a heavy mirror, consider a more flexible epoxy.
- Bonds plastic, rubber, and metal in seconds
- High strength, gap-filling formula
- Resistant to moisture and temperature variations
Pros: Fast bonding, ideal for plastic mirror buttons; Strong and durable bond
Cons: Not designed for glass-to-glass bonds; Can be brittle if exposed to impact
4. Loctite 1363580 Glass Glue: Best for Glass Bonding
Loctite Glass Glue is formulated for glass surfaces, making it a good choice for attaching a glass mirror button directly to the windshield. According to the manufacturer, it is UV resistant and dries clear, so it won’t leave a messy residue. Owner feedback indicates it works well for rear view mirrors that have a glass button, providing a secure hold.
On the downside, this glue requires 24 hours to fully cure, during which the mirror must remain undisturbed. It also bonds less effectively to metal buttons. If your mirror button is metal, look for a metal-compatible adhesive. Additionally, it may not withstand extreme temperatures as well as some other options.
- Specifically designed for glass bonding
- UV resistant, clear finish
- Works on glass, ceramic, and some plastics
Pros: Excellent adhesion to glass; Clear and UV resistant
Cons: Longer cure time (24 hours); Not as strong on metal buttons
5. J-B Weld 50112 PlasticWeld: Best for Plastic Repairs
J-B Weld PlasticWeld is an epoxy putty that can repair broken plastic mirror housings or brackets. Based on our evaluation, it forms a strong bond with many plastics and can be shaped to fill gaps. Once cured, it can be drilled and sanded, making it useful for more complex repairs. Owner reviews praise its strength for structural fixes.
However, this product is not ideal for simply attaching a mirror button to glass; it is designed for plastic repairs. The putty requires mixing and a 25-minute set time, which may be inconvenient. If you need a simple adhesive for mirror attachment, a dedicated mirror adhesive or tape would be more appropriate.
- Bonds and repairs plastic, PVC, ABS, and more
- Can be drilled, sanded, and painted after curing
- Water and chemical resistant
Pros: Versatile repair material for broken plastic parts; Strong and durable once cured
Cons: Not a quick fix, requires mixing and shaping; Overkill for simple mirror attachment
6. Sugru Moldable Glue: Best Flexible Bond
Sugru is a moldable silicone glue that cures into a flexible rubber. It can be used to attach a rear view mirror button, especially in situations where vibration is a concern. The flexibility helps absorb shocks, potentially reducing the chance of the mirror detaching. Owner feedback often highlights its ease of use and versatility for various repairs.
However, Sugru has lower tensile strength than dedicated mirror adhesives, so it is not recommended for heavy mirrors. It also takes 24 hours to fully cure, during which the mirror must be supported. If you have a standard lightweight mirror and want a flexible bond, it can work, but for a permanent strong hold, consider a stronger adhesive.
- Moldable like putty, bonds to glass, metal, plastic
- Remains flexible after curing
- Waterproof and temperature resistant from -60 to 180 degrees F
Pros: Flexible bond absorbs vibration; Easy to apply and shape
Cons: Lower holding strength compared to epoxies; Long cure time and not for heavy mirrors
7. Gorilla 2 Part Epoxy: Best Heavy-Duty
Gorilla 2 Part Epoxy provides a heavy-duty bond suitable for large or heavy rear view mirrors. According to the spec sheet, it sets in 5 minutes and cures in 1 hour, offering a strong, impact-resistant hold. It is gap-filling, which helps if the mirror button is not perfectly flat. Owner reviews note its reliability for demanding applications.
The main downside is the mixing process: you must dispense equal parts from the syringe and mix thoroughly before application. This can be messy and requires precision. Also, once mixed, you have a limited working time. If you need a simpler solution or are not comfortable with epoxy, a tape or liquid adhesive may be preferable.
- High strength bond on metal, glass, and plastic
- Sets in 5 minutes, cures in 1 hour
- Gap-filling and impact resistant
Pros: Extremely strong, permanent bond; Works on multiple surfaces including metal
Cons: Mixing required, can be messy; Not ideal for quick or temporary fixes
Frequently Asked Questions
Can I use super glue to attach my rear view mirror?
Some super glues, like cyanoacrylate adhesives, can work for attaching plastic mirror buttons to glass. However, they may become brittle over time and are not recommended for heavy mirrors. For best results, use a product specifically formulated for rear view mirrors or a high-strength epoxy.
How do I remove old adhesive from the windshield?
To remove old adhesive, use a razor blade scraper carefully on the glass. Apply a solvent like isopropyl alcohol or adhesive remover to soften the residue. Avoid using excessive force to prevent scratching the glass. For stubborn adhesives, a heat gun on low setting can help.
How long should I let the adhesive cure before driving?
Cure times vary by product. Most liquid adhesives require 24 hours to reach full strength, while mounting tapes provide immediate hold. Always follow the manufacturer’s instructions. For safety, wait at least the recommended minimum before driving to ensure the mirror stays attached.
Will the adhesive damage my windshield or defroster grid?
Most rear view mirror adhesives are designed to be safe for automotive glass and will not damage the windshield or defroster grid if applied correctly. However, avoid getting adhesive on the defroster lines, as removal could damage them. Use a precision applicator and clean any excess immediately.
Can I attach a rear view mirror to a windshield with a tinted strip?
Yes, but ensure the adhesive is compatible with the tint film. Some adhesives may not bond well to tinted surfaces. Lightly sand the area or use a primer if recommended. Test in an inconspicuous area first. Many users report success with double-sided tapes on tinted glass.
