Best Metal Filled Epoxies of 2026

"I've relied on J-B Weld for years because the bond is always dependable and long-lasting. The new syringe applicator is much less messy than old squeeze tubes, and it's easy to mix and apply. Even though it costs a bit more, I know exactly what I'm getting every time."

"As a QA/QM/QC engineer with hands-on experience in electronics and machine work, I can say that J-B Weld is on par with industrial-grade compounds. I used it to fix a faucet handle at home, and it's been holding solidly for years with zero failures. When used creatively, this stuff makes repairs that are practically unbreakable."

"I recently used this epoxy to fix a kitchen sink handle with a stripped gear. The instructions were clear and mixing was easy. I was worried about bonding metal to plastic, but a week later the repair is still holding strong. This product really impressed me with its performance."

"I've used J-B Weld KwikWeld Steel Reinforced Epoxy for several repairs, and the bond is incredibly strong and cures quickly. Whether fixing household items or automotive parts, the epoxy's versatility and durability have made it an essential part of my toolkit. Highly recommended for anyone needing a reliable adhesive."

"I applied JB Weld to fix a broken laptop hinge and was genuinely impressed. Mixing and applying the epoxy was straightforward, and I had enough time to position everything perfectly.

"I've used this epoxy on everything from home repairs to automotive fixes, and it always delivers a rock-solid, permanent bond.

I’ve had great results on metal, plastic, and ceramic, and the high heat resistance makes it a go-to for engine and exhaust repairs."

"For me, JB Weld is the ideal solution for casual repairs—the smaller tubes are convenient, and the epoxy hardens like steel. I’ve used it for multiple projects, and it never disappoints. It sands well, dries to a grey color, and as long as you give it time to cure, it really does the job."

"Absolutely impressed—this epoxy bonds metal, wood, and more with incredible strength. The steel-reinforced formula means repairs last, and the application is smooth even for DIY projects. I consider it a must-have for home or auto fixes—it always delivers professional results."

"I've used this epoxy for years and it remains one of the best for fabrication projects. Mixing and application are straightforward—just remember to use a shallow, wide container. I even reached out to the manufacturer about shelf life, and they confirmed it's good for 5+ years. I've also thinned it with denatured alcohol to use as a wood sealer, which worked beautifully. Just stir it well and use small batches for best results."

"I switched to this product after trying Gorilla Glue syringes, and I'm glad I did. Mixing is easier with the two-bottle format, and I found the application much smoother and less messy. The glue dries quickly and holds strong, especially for projects like installing T-tracks on workbenches. I learned to work in smaller batches to avoid it getting too gummy. A little goes a long way, making it a great value."

"This epoxy is perfect for sealing my 3D prints—it gives me plenty of working time and delivers a clear, glossy finish. Just be aware that it can cure a bit thicker than expected on flat surfaces, so plan for that extra layer. Mixing and application are easy, and the result is exactly what I needed."

"As a hobby machinist, I messed up my mill bed with a dropped end mill, leaving a long divot. This product filled in the damage perfectly after careful prep and filing. The machine is back in action, and I have no regrets trying this instead of JB Weld. Great performance and strong repair!"

"We had issues with our SKB keyboard case's holders constantly coming off. Instead of shipping it for repair, I used this epoxy, and the holders have stayed put for two years, even with regular vertical storage. Saved money and hassle!"

"When my MSI laptop hinge broke, I used this epoxy and followed the directions. After curing, the hinge was rock-solid—just like new. It’s been holding up perfectly for weeks, and I’m confident my laptop's life is extended. If the other hinge fails, I know exactly what to do. I never thought I’d be so impressed by epoxy, but this is 100% worth it."

"I’ve tried many adhesives, but this one stands out. It’s strong, easy to work with, and sets up fast. I’ve used it on both metal and plastic repairs—each bond is holding under stress. The quick cure time is a huge plus, and once it’s set, it’s as tough as steel. This is a must-have for reliable, lasting fixes."

"I needed to fix the handle on my favorite aluminum tea cup. After properly prepping the surfaces and using this epoxy, the bond was secure and solid by morning—no wiggle at all. The set time is quick, so you have to be ready, but the results on aluminum are impressive if you follow the instructions."

"Whenever I need something to be absolutely immovable, I go straight for this epoxy. The bond is unbelievably strong—recently, it turned a threaded insert into a permanent fixture. I really appreciate the 5-minute set time, which gives just enough time to get everything in place without dragging the process out. The syringe makes it simple to get the right mix without guessing, and any squeeze-out dries clear, so it doesn’t look bad. Once cured, it sands and drills nicely. Compared to typical super glue, this stuff is on another level for strength, especially where vibration or stress is involved. It can be a bit messy if you’re not careful, and it’s not the cheapest glue out there, but for important jobs where failure isn’t an option, it’s worth every penny."

"I recently had to fix a custom resin sculpture that broke into four pieces. Using just a moderate amount of this epoxy, I was shocked by the rigidity and strength it provided—my sculpture is now sturdier than before the repair! The thick, honey-like consistency fills gaps well, and it cures to a clear, glassy finish. It bonds with metals, wood, resin, and even 3D printed plastics. I’d recommend gloves and some acetone for cleanup before it cures, but overall, the results are truly impressive—it really lives up to the ‘gorilla strong’ name."

"My experience with this epoxy matched the description: rapid, durable bonding with a clear finish. The 5-minute set time is accurate, so you need to work quickly. It’s perfect for small repairs and delivers a sturdy, lasting hold. The only minor issue is that it can be a little messy to dispense—sometimes there’s a little overflow, so I keep paper towels nearby. Overall, it’s a reliable product that stands up to tough jobs."

"After my cat broke a beloved ceramic vase, I tried regular glue but the cracks were still very visible. With this putty, I was able to fill the gaps and smooth out the damage so well that you can barely tell it was ever broken. Now, the vase looks almost new and sits proudly back on display. I even experimented with making some trinkets—this product is incredibly versatile and easy to work with!"

"I used this to repair some cracks in my swimming pool and it worked flawlessly, even underwater. The instructions were straightforward, and once I mixed the two parts, it became off-white and easy to apply. After curing, the bond was so strong that the repairs were almost invisible. Saved me hundreds on professional repairs—excellent value!"

"When I had a leak in my water pipe, this putty made the fix simple and quick. The two-part mix was easy to handle and didn’t smell bad. It hardened within a day and sealed the leak perfectly.

"I used this putty to bond rocks and wood in my aquarium, and I feel confident it holds securely even with fish in the tank. The only challenge was getting it off my gloves, and it can leave visible spots, but overall the strength and reliability really impressed me."

"My work refurbishing cast iron led me to try this product on a severely cracked antique pot. I found that a small amount goes a long way and the putty filled the large crevice perfectly. It dried quickly, and after painting, the repair was watertight and solid. The white color is easy to cover, so aesthetics aren't a problem if you plan to repaint. I'm thrilled to have plenty left for future projects."

"This product has been a real lifesaver for household repairs. It worked perfectly to patch a gap in bathroom tile and seal baseboards against ants. Just a heads-up, it doesn't always stick well to wood, but for most surfaces, it's reliable and handy to keep stocked."

"I found this glue to be extremely strong and easy to work with. After using it to repair a broken metal piece, the bond was so tight it felt just like it had been welded. What really stood out was the durability and waterproof qualities, making it ideal for even outdoor and marine repairs."

"This was the only adhesive that worked for fixing my office chair after trying several others. The final bond strength and smooth finish are excellent, but it’s crucial to let it cure fully. I waited 48 hours and the results were perfect."

"While the glue itself did the job for my automotive trim, the tube dispenser design could be improved. Since the plunger isn’t attached, it’s easy to dispense too much, which can be messy. On the bright side, you can clean up with lacquer thinner if needed."
