Permatex Rearview Mirror Adhesive, Adhesive .3ml/Primer

This is another offering from Permatex, and while the product description is a bit less detailed than the Extreme Professional version, it’s a widely available and popular choice for basic mirror reattachment. It comes as a two-part system with an adhesive and a primer, which is a common and effective method for these types of bonds. I’ve used this one in a pinch before, and it gets the job done reliably.

Helpful Comparison Insights

When choosing the best adhesives for rear view mirrors, you’ll notice a few key differences. Most top-performing options, like the Permatex 81840, J-B Weld MirrorWeld, and Loctite 37438, use a two-part system with an activator or primer. This isn’t just a gimmick; it’s crucial for achieving a chemical bond that holds up. The activator cleans and prepares the glass surface, allowing the adhesive to form an incredibly strong bond with the metal button. Permatex 81840 takes this a step further with its medical-grade towelette for precision.

Speed of repair is another significant factor. If you’re in a hurry, the J-B Weld MirrorWeld stands out with its 1-minute set and 1-hour cure time, making it incredibly efficient. The Loctite 37438 is also very fast, achieving handling strength in seconds and full strength in 15 minutes. The Visbella kit also boasts “Quick Repair Functionality,” which I found to be true. While all these options are faster than traditional epoxies, the J-B Weld and Loctite truly excel in getting you back on the road quickly.

OEM approval is a huge trust indicator. Loctite 37438 is approved by major manufacturers like GM, Ford, and Daimler-Chrysler, which speaks volumes about its tested performance and reliability. If you want the peace of mind that comes with industry validation, Loctite is a top contender. The Permatex 81840 also mentions an “OEM specified formula,” reinforcing its professional-grade quality.

For versatility, the Visbella Rearview Mirror Adhesive Repair Kit really shines. Its ability to bond metal, glass, ceramics, and more makes it a multi-purpose tool for your garage, beyond just mirror repairs. While dedicated mirror adhesives are best for mirrors, having a product that can do more is a nice bonus. However, if your only concern is getting your rearview mirror back on, the specialized kits will offer the most optimized performance for that specific task.

Finally, consider the ease of application. While two-part systems might sound complex, most are designed for DIYers. The Permatex 81840‘s towelette minimizes mess, and the clear instructions on all these products ensure a smooth process. Even the standard Permatex Rearview Mirror Adhesive with its primer system is straightforward and reliable for a basic fix.

Final Verdict

Choosing the best adhesives for rear view mirrors really comes down to your priorities.

If unquestionable strength and OEM-level trust are paramount, the Loctite 37438 Rearview Mirror Adhesive Kit is a phenomenal choice, especially with its approvals from major auto manufacturers. It’s fast and gives you peace of mind.

For those who prioritize a professional-grade bond with clean application, the Permatex 81840 Extreme Rearview Mirror Professional is incredibly effective. Its two-part system and medical-grade towelette make it feel like a truly robust repair.

If speed is your ultimate concern and you need your mirror back on and ready to go in minutes, the J-B Weld MirrorWeld with its 1-minute set time is your best bet. It delivers powerful adhesion in record time.

For a versatile adhesive that’s strong enough for your mirror and useful for other household repairs, the Visbella Rearview Mirror Adhesive Repair Kit offers a compelling package with its superior strength and broad application range.

And finally, for a dependable, no-frills, and cost-effective solution that simply works well, the standard Permatex Rearview Mirror Adhesive is a solid, reliable option that many DIYers have trusted for years.

Comprehensive FAQ Section

Q1: Why did my rearview mirror fall off in the first place?
A: Rearview mirrors often detach due to extreme temperature fluctuations (hot sun, then cold nights), vibrations over time, or even minor impacts. The original adhesive can degrade or weaken, causing the mirror to separate from the windshield. Using one of the best adhesives for rear view mirrors can prevent future issues.

Q2: Can I use super glue or epoxy to reattach my rearview mirror?
A: While super glue (cyanoacrylate) or standard epoxy might seem like a quick fix, they are generally not recommended for rearview mirrors. They don’t typically provide the flexible, durable bond needed to withstand the vibrations, temperature changes, and specific stress points that a rearview mirror experiences. Specialized rearview mirror adhesives are formulated for these exact conditions and will offer a much safer and longer-lasting bond.

Q3: How do I properly prepare the windshield surface before applying the new adhesive?
A: Surface preparation is crucial for a strong bond. First, carefully scrape off all old adhesive from both the windshield and the mirror button using a razor blade or a utility knife (be extremely careful not to scratch the glass). Then, clean both surfaces thoroughly with rubbing alcohol or a specialized glass cleaner to remove any grease, dirt, or residue. Allow it to dry completely before applying the rear view mirror adhesive. Many kits include a primer or activator for this step, which you should use according to the instructions.

Q4: How long does the adhesive take to cure, and when can I reattach the mirror?
A: Cure times vary significantly between products. Some, like the J-B Weld MirrorWeld, offer a handling strength in 1 minute and a full cure in 1 hour. Others might recommend waiting 15 minutes to an hour for handling strength and up to 24 hours for a full cure. Always follow the specific instructions on your chosen rear view mirror adhesive kit. It’s best to wait for the recommended full cure time before hanging the mirror back on the button to ensure maximum strength.

Q5: What should I do if the adhesive doesn’t hold?
A: If the adhesive doesn’t hold, the most common reasons are improper surface preparation (old adhesive remaining, not clean enough), incorrect application (not enough adhesive, not using the primer/activator correctly, or not applying enough pressure during initial bond), or environmental factors like extreme cold during curing. You’ll need to remove all the adhesive, thoroughly clean both surfaces again, and reapply the rear view mirror adhesive following the instructions precisely. Consider using a different brand if you suspect the product itself was faulty.

Q6: Can these adhesives be used on tinted or coated windshields?
A: Most rearview mirror adhesives are safe for use on tinted or coated windshields. However, it’s always a good idea to check the product’s specific instructions or contact the manufacturer if you have a unique type of windshield coating (e.g., aftermarket tints, specialized UV coatings) to ensure compatibility. The bond usually forms on the glass surface itself, underneath any tint film.

Q7: How much adhesive do I need? Are these kits single-use?
A: The kits typically come with enough adhesive for one or two mirror reattachments. Most rearview mirror adhesives come in small, single-use vials or tubes designed to be used completely once opened, as exposure to air can cause them to cure. It’s rare to have enough left over for a second repair months down the line.
