1. Permatex 81848 Rearview Mirror Adhesive: Top Pick
Permatex 81848 is a two-part epoxy designed specifically for rear view mirrors. In our evaluation of spec sheets and owner feedback, it consistently delivers a strong bond that withstands vibration and temperature swings. The syringe design makes mixing precise and mess-free, and the 5-minute cure time means you can reattach your mirror quickly. However, the 0.5 oz tube is small; if you need to glue multiple mirrors or have a large mirror, consider a larger kit.
Based on owner feedback, a small number of users reported the bond failing after a year in very hot climates. If you live in an area with extreme heat or need a heavy-duty solution for a larger mirror, you might want to explore other options with higher heat tolerance.
- Contains both resin and hardener in a single syringe for easy mixing
- Cures in 5 minutes, reaches full strength in 24 hours
- Works on glass and metal, temperature range -40 to 180°F
Pros: Fast curing time reduces wait; Strong bond holds even in heat
Cons: Small tube may not be enough for multiple mirrors
2. Gorilla Epoxy Clear: Runner Up
Gorilla Epoxy Clear is a well-known general-purpose epoxy that works excellently for rear view mirrors. We compared its spec sheet to others and found it offers strong adhesion and a clear finish that blends with the glass. The 0.85 oz syringe provides a bit more material than the Permatex, making it a good value. Owner feedback highlights its reliability for mirror reattachment, though some note that the bond can be brittle if too much is applied.
One limitation is that while it sets in 5 minutes, full cure takes 24 hours, so you need to keep the mirror supported that long. If you need a faster turnaround, the Permatex might be better. Also, it’s not specifically formulated for automotive mirrors, so for extreme conditions, a dedicated mirror adhesive may be preferred.
- Clear formula dries invisible for a clean look
- Bonds to glass, metal, plastic, and more
- Waterproof and impact resistant
Pros: Versatile adhesive for other repairs; Clear finish is aesthetically pleasing
Cons: Longer full cure time (24 hours) than some competitors
3. Loctite 234752 Rearview Mirror Adhesive: Best for Heat Resistance
Loctite 234752 is a urethane-based adhesive that stands out for its heat resistance. In our research, it is often recommended for vehicles in hot climates or those with dark-tinted windshields that absorb more heat. The included primer improves adhesion on smooth glass surfaces. Owner feedback indicates it holds well even in summer heat, though some users found the 10-minute set time inconvenient.
However, the extra step of applying primer and the longer cure time may be a drawback for those wanting a quick fix. If you don’t face extreme heat, a simpler epoxy might be sufficient. Also, the 0.7 oz tube is on the smaller side, so check your mirror size.
- Urethane formula designed for high-temperature environments
- Resists vibration and shock
- Includes primer for better adhesion on glass
Pros: Excellent heat resistance up to 200°F; Primer included ensures strong bond
Cons: Longer cure time (10 minutes set, 24 hours full); Primer adds an extra step
4. 3M 08682 Rear View Mirror Adhesive: Professional Grade
3M 08682 is a professional-grade adhesive that we found frequently recommended by auto body shops. Based on spec sheets, it offers high shear strength and reliable performance. Owner feedback from DIYers is positive, but some note that the tube is quite small and may not be enough for larger mirror buttons. It’s a solid choice if you want a proven product from a reputable brand.
However, the higher cost per ounce and small size make it less economical for occasional use. If you only need to glue one mirror and want professional results, it’s a good pick. But for multiple repairs or budget-conscious buyers, other options offer better value.
- Used by automotive professionals
- High shear strength for heavy mirrors
- Temperature range -40 to 180°F
Pros: Trusted brand in automotive repair; Strong bond for heavy mirrors
Cons: Small tube size per application; More expensive per ounce than competitors
5. J-B Weld 50132 ClearWeld: Best Value
J-B Weld ClearWeld is a versatile epoxy that offers great value for the price. In our comparison of cost per ounce, it stands out as one of the most economical choices. Owner feedback shows it works for mirror reattachment, but the 25-minute set time means you must hold or tape the mirror in place longer. It’s a good budget option if you don’t mind the wait.
However, because it’s not formulated specifically for rear view mirrors, it may not perform as well under extreme temperature fluctuations. Some users reported the bond weakening over time in hot cars. If you need a long-term solution in a harsh environment, consider a dedicated mirror adhesive.
- Clear formula dries transparent
- Bonds to glass, metal, and plastics
- Low cost per ounce
Pros: Very affordable for the amount; Clear finish looks clean
Cons: Longer set time (25 minutes) requires patience; Not specifically designed for mirror adhesion
6. Sikaflex 252 Rear View Mirror Adhesive: Heavy Duty
Sikaflex 252 is a one-part polyurethane adhesive designed for structural bonding. In our evaluation, it provides an exceptionally strong bond and is often used for mounting heavy mirrors or in commercial vehicles. The large tube is great if you have multiple mirrors or other projects. However, it requires 24 hours to cure fully and you need to support the mirror during that time.
This product is overkill for most passenger cars. The long cure time and need for clamping make it less convenient. Also, the adhesive is not clear, so it may be visible if not applied neatly. If you have a standard car mirror, a simpler epoxy is easier to use.
- Large tube for multiple applications
- Extremely strong bond on glass and metal
- Excellent vibration dampening
Pros: Very durable for heavy mirrors; Large quantity for multiple repairs
Cons: Long cure time (24 hours) and requires clamping; Not clear, dries black or gray
7. Astro Pneumatic Tool 4460 Mirror Adhesive: Quick Fix
Astro Pneumatic 4460 is a quick-fix adhesive that cures in just 3 minutes. It uses a unique crush-and-shake mechanism that eliminates mixing. Based on owner feedback, it works well for temporary repairs or when you need the mirror back on immediately. However, we found that its long-term durability is not as high as epoxy options, with some users reporting failure after a few months.
If you need a permanent solution, this may not be the best choice. It is best as a stopgap until you can apply a stronger adhesive. Also, the 0.5 oz tube is small and may not provide enough for a secure bond on larger mirrors.
- Ultra-fast 3-minute cure time
- No mixing required, just crush and shake
- Designed for rear view mirrors
Pros: Fastest cure time among picks; No mixing mess
Cons: Lower durability reported by some users; Small tube size
Frequently Asked Questions
What is the best adhesive for gluing a rear view mirror?
Based on our research, the best adhesive is a two-part epoxy specifically designed for rear view mirrors, such as Permatex 81848. It offers a strong bond, fast cure time, and good temperature resistance. For extreme heat, consider Loctite 234752.
Can I use super glue to attach a rear view mirror?
Super glue (cyanoacrylate) is not recommended because it becomes brittle under vibration and temperature changes, leading to failure. It also does not fill gaps well. A two-part epoxy or urethane adhesive is much more reliable.
How long does rear view mirror adhesive take to cure?
Cure times vary by product. Most epoxies set in 5-10 minutes but require 24 hours to reach full strength. Some fast-curing options set in 3 minutes, but full cure still takes several hours. Always follow the manufacturer’s instructions.
Do I need to remove the old adhesive before applying new glue?
Yes, for a strong bond you must remove all old adhesive from both the mirror button and the windshield. Use a razor blade or adhesive remover, then clean the surfaces with alcohol. This ensures proper adhesion.
Will rear view mirror adhesive work on a heated windshield?
Most adhesives work on heated windshields, but the heat can affect curing. Ensure the windshield is cool before application. Some adhesives have temperature limits; check the spec sheet. For heated windshields, a urethane-based adhesive like Loctite 234752 may be more suitable.
Our Verdict
After researching and comparing the top adhesives, our top pick is the Permatex 81848 Rearview Mirror Adhesive for its fast cure, strong bond, and ease of use. For those needing extra heat resistance, the Loctite 234752 is a solid runner up. Choose based on your climate and patience for cure time.
