J-B Weld 8281 Professional Size Steel Reinforced Epoxy - Hardener and Steel Pack - 10 oz

Sets up quickly and cures overnight. Smells during mixing and application, but it will bond whatever it touches. Not for use on items subjected to high heat. Works excellent on plastics and most metals. Make sure to have clean contact surfaces. Great value for the job it does. I have a large telescope that weighs over 40lbs. One of the tripod mounts cracked during transport to a site. I glued the pieces together and it has stayed bonded for 24 years. Specifically a G5 equatorial German Mount tripod with a C8 Schmidt-Cassegrain optical tube.

Had a piece of cast iron that needed a fix. This stuff is fantastic! Works great. Easy to use. Fast shipping. No issues. Brand New. Yes I would purchase again.

This product works well on ceramic, metallic, and other mixed media surfaces and is handled on heavy duty. It is easy to use, and you can take time to use it in the right spots. Only you need to care for the color. It will be dark gray when dries, and the texture is hard plastic.

I love this stuff. Use it a lot. I like that it is a slow set which allows me to do a complicated repair and because it is slow, the results are very strong. Sticks to most everything (not polyethylene of course). I've used it to fix plastic items and metal items. With plastic I often embed metal pins or needle pieces in the plastic (after drilling tiny holes) to enhance the shear strength. This steel filled epoxy is really tough. It is easy to mix whether by weight or volume, both are 1:1. I did have it come a bit late but they informed me of that -- probably some supply chain issue.

Great product !

The Epoxy works well with many materials. It does have a total cure time of 24 hours. On the front end, planning, clamping, mixing, and assembling the material is time dependent. Any excess epoxy dries to a dark gray color and my wife was not satisfied with my repairs to her china container. It was my mistake in not wiping off the excess after I had assembled the parts. This is the jumbo pack, so you have plenty to work with.

Excellent quality filler for wood & metal. I wish it would be available in larger quantity.

I was a diesel mechanic for 18 years. This particular slow curing epoxy is well known for the ability to repair things and save time and money.However, to get it to work you need to theurgy clean the area and degrees it with something like brake cleaner, so it is totally dry. Next is follow the directions for the curing time before putting a load or pressure on the repair.Also, the curing time changes with temperature. Cold temps take longer. I don't live in an area where it snows so I don't know at what temp it would not cure or take some really long time to cure. I just know that the longer you give it to cure the more likely the repair will work.One story from work that sticks out in my mind. Engines have stamped Sheetmetal core/freeze plugs on them and eventually the leak. much more so with the plated steel ones than the brass ones but I have seen even the brass ones have electrolysis eat through them or hole they go in rust through.In this case on a large forklift engine right at the rear of the cylinder head was a large freeze plug leaking. You could not just install a new one because the transmission bell housing went up and covered half of it.To do the fix properly the cylinder head would have had to come off or the bell housing backed off enough to do that. The vehicle had to be at work making money for the company and just paying me to do it would in of itself be a substantial cost.So, I got in there and cleaned the area out, got it all degreased with brake cleaner and in a few staged filled the whole are in with JG Weld steel filled epoxy and let it cure overnight and the next morning it was ready to go. Years ago when I changed jobs that vehicle was still working with no leak in the repaired area.The caution is simply that how you do the job is extremely important. Don't expect the JB Weld to stick to oily or greasy surfaces or surfaces where there is loos crud, rust and so on. You have to do your part to make it work.
