8271 KwikWeld Professional Size Steel Reinforced Epoxy Twin Pack - 10 oz.

I use the heck out of this stuff. It works for just about anything that needs a strong glue or filler. Number 1 quick-set epoxy glue, in my opinion. Reminder - proper surface prep is essential for maximum holding strength. Sand and clean all surfaces before gluing or filling.

Terrific product, thick, viscous, won’t easily run on a bit of any angle, set up fast, holds really well. It has terrific adhesive properties on properly prepared hard plastic like the back of a bumper, it was so thick it didn’t leak through the crack in the bumper and it set up fast. Someone hit the trim under my rear bumper, probably with a trailer hitch and split the trim piece in two. It was simple, low level cosmetic damage, nothing serious. But I didn’t want the crack to enlarge so a repair was in order. Insurance was out, that’s like stealing from myself because whatever the repair costs, I’ll pay in increased premiums plus the deductible. I carefully lined up the split plastic trim and then got behind the bumper, cleaned it with VMP Naptha and sanded the plastic with 150 grit paper and cleaned with VMP Naptha again. I have stainless steel mesh on hand and cut a couple of 2x2 inch pieces. I mixed up the J-B Weld and embedded the mesh in a thick coat of the epoxy and placed it over the crack in 2 places on the back side of the bumper. The photos show the original damage up close, the wider shot shows the “fix” and the other photo shows the inside of the back of the bumper. The crack in the bumper is still visible but it’s hard to see unless you’re looking for it and it won’t enlarge due to the J-B weld “fix”. I plan to add one coat of the J-B Weld from behind after the first batch sets up overnight. Great product!

There are many 2-component epoxies that will get hard. JB Weld gets even harder, but more than that, it is easy to apply and work with when it is fresh-mixed, much more that others that I have used. I use this stuff constantly and it has never failed me yet, even extreme uses. Example: my electronic toothbrush worked well, but the rubber push-button switch quit working. Opened it up, and the little "finger" of plastic that pushed down on the switch button on the small circuit board broke, so when I pushed the rubber button it didn't make contact. A tiny dab of JB size of a pin head on the circuit board button hardened enough so that when I push it makes contact again. Crazy. Broke the side-view mirror on my car, cracked part of the black plastic housing. The motor still worked, but there was a gaping hole in the housing. I smoothed in a large gob of JB and you can't tell anything was missing. Next day I painted it with black caliper paint and you can't tell the difference. That is how smooth you can work this epoxy. Great stuff, use it for repairs. Never failed yet.

Worked great on a project

Pretty strong and reliable epoxy. It bonds well and sets quickly, which makes small repairs simple. The mix is easy to work with, though you need to move fast before it starts to cure. Feels sturdy once hardened and holds up well — a handy thing to keep around.

If you are looking for a quick setting strong epoxy, this is the one for you. It may not be the perfect solution for everything, however I have been using JB for years and never had an issue.

JB weld works great for a good strong bond when it comes to adhering things back together. Created a strong bond on a variety of things. Follow the directions to mix it properly and apply accordingly. Works great.

Never fails! This stuff would definitely be in the Mcgyver go bag.

Very impressed with J B Weld sealed my car radiator perfectly

Tengo mucho tiempo usando el producto, es de lo mejor en pegamentos, se puede usar hasta en motores de auto, un gran producto, como lo uso a menudo por eso pido el tamaño mas grande (Hay mas chicos si no ocupan gran cantidad)

I recently used the J-B Weld KwikWeld Professional Size Epoxy for a repair on my metal fence, and I couldn't be more impressed. The epoxy sets in just 6 minutes and cures fully in 4-6 hours, allowing me to complete the project in a single afternoon. Once cured, the bond is incredibly strong, withstanding the outdoor elements without any signs of weakness. The dark grey finish blends well with metal surfaces, and the epoxy can be sanded and painted over for a seamless look. This product is a must-have for any DIY enthusiast or professional looking for reliable and quick-setting epoxy!
