J-B Weld 50139 Plastic Bonder Body Panel Adhesive and Gap Filler Syringe - Black - 25 ml

I was replacing windshield wiper refills and one of the plastic covers cracked in a few pieces. Since it was just the cover part and the wiper still worked fine and i still have a bunch or blade refills i decided to try and fix the cracked cover. I bought this 2 part epoxy since its black in color and its outdoor use. It mixes up easy but it gets everywhere. I was wearing disposable gloves thankfully or my hands would have been covered. I was working with small broken pieces so just couldnt avoid not touching the epoxy. It sets up pretty fast. The mixed epoxy seems to start setting up right after mixing. It gets hot too. I only mixed a small amount each time to have longer to work with it. Seems to cure solid. Sticks to everything. I used a little too much and had trouble fitting the wiper back on the arm so had to sand some down. It sanded easily with a metal file. Hopefully it lasts along time and doesnt break down in the sun. I'll update if theres any issues with it. - Update: Found another use for this epoxy. Theres a small plastic bracket inside the bottom of my cars front bumper that was loose and rattling around. I finally got around to seeing what it was exactly. Looks like it had broken off, im guessing since the bottom of the bumper is so low to the ground I must have hit a curb. The bracket is normally held to the bumper cover with a rivet and since i dont own a rivet tool I figured i can install a nut and bolt instead. The problem is when the bracket is fit onto the inside if the bumper theres no way to reach around to put the nut on, probably why a rivet was used. I used this epoxy to install the nut on so it doesnt move. It ended up working great. I cleaned the plastic really well with rubbing alcohol then sanded it a little to roughen up the surface with a small metal file. I had to hold the nut with my finger while inserting the small bolt, mixed up a small amount of the epoxy then poured it all around the nut. Carefull not to get any epoxy on the bolt so I could unscrew it back out so I can then install it on the bumper. I let it cure for a few hours just to be sure. Was able to fix it for the cost of a nut and bolt. And I still have plenty of the epoxy left for other things.

This is absolutely the best adhesive you can get for plastic bonding. I can’t recommend it higher. I had a cracked telescope tripod leg plastic piece which needed to fixed. I actually tried to order the actual piece from the vendor, no cigar, then the entire leg with the piece, again no cigar - they wanted me to buy the entire tripod which would have cost hundreds of dollars. Someone told me about J-B Weld and said it would work 100 percent but of course, the doubter I am, I did not believe them. My telescope mount weights about 35 pounds evenly spread on 3 legs and this piece was on one leg. Took it off the tripod leg, glued it, and waited an hour longer than required by the directions - you know doubter that I am, and what can i say the adhesive/glue had hardened into something stronger than the plastic piece iteself. Just amazing stuff and again I highly highly recommend it. I am amazed at the strength of the material and what it does - go out and get some just to have around the house.

The J-B Weld 50139 Plastic Bonder Body Panel Adhesive and Gap Filler Syringe has become a staple in my garage for automotive and household repairs. Here’s why I’m giving it a 5-star review: 1. Incredible Bonding Strength: This adhesive is extremely strong and has proven to hold up well under pressure. I used it to repair a cracked plastic body panel on my car, and it created a bond that felt just as strong as the original plastic. Whether you’re fixing bumpers, body panels, or other plastic components, this adhesive will keep them firmly in place. 2. Easy to Apply: The 25ml syringe is a convenient and easy-to-use applicator. It’s precise, which means no mess or waste. The mixing ratio is simple, and once you combine the resin and hardener, it’s ready to go. The syringe applicator allows for targeted application, so I could apply it exactly where I needed it without spilling. 3. Quick Curing Time: I was pleasantly surprised by the fast curing time. It only takes about 15 minutes to set, and full strength is achieved in a few hours. It’s perfect for quick fixes that don’t require hours of waiting. I was able to complete my repair and get back to driving without much downtime. 4. Versatile and Multi-Purpose: Not only is this great for automotive repairs, but it’s also perfect for other projects around the house. I’ve used it for plastic, fiberglass, and even metal repairs, and it holds up incredibly well. The bond is weather-resistant, which is a huge plus for outdoor or exposed repairs. 5. Durable and Long-Lasting: Once it cures, the bond is strong and durable. I haven’t had any issues with the adhesive breaking down or losing its strength, even after exposure to heat, cold, and moisture. It’s holding up incredibly well on the body panel I fixed, and I’m confident it will last for the long term. 6. Works as a Gap Filler: Another standout feature is its ability to act as a gap filler. The product fills in gaps between parts, which helps create a smooth, even surface once it dries. This is great for automotive bodywork, where filling in small cracks or gaps is necessary for a seamless repair. Final Thoughts: The J-B Weld 50139 Plastic Bonder Body Panel Adhesive and Gap Filler Syringe is a game-changer when it comes to repairing plastic components. It’s strong, fast, and easy to use.

The Simply 50139 J-B Weld PlasticBonder in black was perfect for a minor repair on my first 4 Figures collectible statue. It bonded strongly and seamlessly, matching the black finish so well that the repair is barely noticeable. The adhesive sets quickly and cures to a tough, durable finish, which is essential for delicate collectibles. The precision applicator made it easy to apply exactly where needed without mess. If you have small plastic repairs, especially on collectibles or detailed items, this product is a fantastic choice for a reliable and clean fix.

Prima lijn, hard uit in de opgegeven tijd en is makkelijk te verwerken, ook de afsluitbare dop is fijn omdat je meestal maar kleine hoeveelheden gebruikt.

Bought it to repair the windshield pillar on my car. After mixing the product it takes around 20 to 30 minutes to start becoming harder. After an hour it hardens and it has a little rubbery texture. I sanded it and painted it afterwards, great result and easy to use.

Works on my plastic real well
