Durable & Functional
Great product and exactly as described. It arrived quickly and was packaged well. Quality exceeded my expectations for the price. Very tight bond and quick dry. I would definitely order this again and recommend it to others.

New go-to glue.
Love this stuff. Works on seemingly everything; wood, plastic, those little angle figurines that get their heads knocked off, glasses, etc. it does take a full 30-60 secs of pressure between pieces to adhere but then holds very well

Strong, reliable, and truly waterproof!
I used this J-B Weld SuperWeld Glue first on my walking cane — a heavy metal handle that screwed into a metal tube. The original connection was a bit loose, so I added just two tiny drops of glue on the thread. It bonded instantly and now holds rock solid — no wobble, no movement, even after the cane fell a few times. Later I used it again to attach small metal caps to my bathroom sink — metal to ceramic — where there’s always moisture and water around. I cleaned and dried the area first, glued the caps, and they’ve stayed firmly in place ever since. The glue hasn’t softened or failed despite constant humidity. It sets fast, has no strong odor, and forms a clear, strong, waterproof bond. Excellent product for quick, durable fixes — absolutely five stars from me!

It can be used in home, and I also used it to fix the wiring for my car dashcam. Hasn't fallen off so far.

Wow! This stuff really works and quickly!
I have two cast metal O gauge model train couplers that I found in boxes I had purchased on eBay. Once I got past my anger, I moved onto repair. I cleaned both sides of the broken parts with acetone and a tooth pick and wiped them clean. I then applied a well know two part epoxy and let them set and dry. After they had set overnight I tested them with finger pressure only. One set held, but the second set failed instantly. I then checked Amazon for metal to metal bonding agents and found JB Weld Superbond Professional glue. I had used JB weld in the past to fix a broken bathroom cast light fixture, but that was a two part epoxy that worked very well. But this was a new JB Weld product that I was unfamiliar with. It is a cyanoacrylate based product that is fast drying. I cleaned both parts, again with acetone and scraped them with the tip of a toothpick to soften and remove the old epoxy and wiped them clean with a clean cloth. I then applied the JB Weld Superbond professional to both ends of the break and simply hand held them in place for about 5 minutes maintaining continuous pressure. I then released the pressure and let the part sit for about an hour and shook it gently. No movement. The package says it fully cures in 24 hours. Well being an impatient sort, I got up the next morning, 19 hours later and applied pressure to both sides of the break, half expecting instant failure. I was pleasantly surprised to find the joint was rock solid. I was amazed that two small cast metal pieces could be bonded with such strength! This “JB Weld Superweld” is amazing and worth a try!
