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. I’ve used it for a number of projects and have always been impressed with the results.

This is a really great product. I snapped the electric charging cover off my vehicle while back out of my garage (doh!). When researching how to connect the cover back to the piece on my EV, I came across this product. Gave it a try because, if it didn't work, I wasn't going to be out too much money. The replacement charging port cover is over $250.After spreading the epoxy glue around all the surface areas that connect the charging port cover and the connecting arm on my vehicle, left it to cure and bond overnight in the garage in 40F weather. The next day, I went to open the charging port cover SLOWLY, waiting for it to flex and break off. This epoxy glue worked like a champ and it is as solid a fix as I've seen it. If there's other plastic items that break in the future, JB Weld is going to do the job and save the day.Saved my $250 + labor charges to replace this. Best value I've spent in a LONG time.

I used this to repair the plastic mounting stem for one of the rear round shaped turn signal lights on the back of my tractor. The stem had broken resulting in the plastic light lens flopping over and hanging by it's wires. Kubota wanted over 75 bucks for a new light. This stuff did the trick and the stem is now secure with the lens strongly supported. To top it off the stem is black plastic- the same color as the bonding agent- so the repair is not even noticeable. I'm almost hoping something else breaks so I can use up the rest and it doesn't go to waste!

When I removed the lid, it shot out like a geyser, dousing my clothes in a black liquid that it’s impossible to remove. This unfortunate incident occurred with a new pair of clothes that I’m currently wearing, so please be cautious.

The only wrist mounts for my large cell phone use rubber bands to keep it attached and they block the camera's from being used. I printed a test holder that would grip my phone with it's rubber Otter case in cheap light grey plastic several times until I got the right fit. Then I printed the finished holder in dark Navy ASA plastic. I cut the rubber bands off of my wrist mount and used the JB-Weld Plastic Bonder to glue the ASA holder to the rubber base of my old wrist mount. I now have the perfect wrist mount holder for my phone that doesn't interfere with the camera's when rotated into position. This was very easy to mix and apply. It set up nice and solid.

It sealed the side of my bumper tight and solid

Worked great for a custom radio install
