The World's Strongest Bond for Heavy-Duty Professional Repairs

The J-B Weld 8281 Professional Size Steel Reinforced Epoxy is the supersized version of the legendary "Original Cold Weld" system, designed for substantial industrial, automotive, and marine projects. This two-part epoxy system provides a viable alternative to torch welding, creating a permanent bond that is stronger than steel itself. With an incredible tensile strength of 5020 PSI, this formula is engineered to handle the toughest repairs on metal, iron, concrete, and more, ensuring that your fix isn't just temporary, but a long-lasting structural solution.

Versatility and durability are at the core of J-B Weld's performance. Once mixed at a simple 1:1 ratio, the epoxy sets in 4-6 hours and achieves a full, rock-hard cure in 15-24 hours. After curing, the material transforms into a dark grey, metal-like substance that can be drilled, tapped, machined, filed, sanded, and painted to match the original surface. It is fully waterproof and resistant to petroleum, chemicals, and acids, and—unlike fast-setting alternatives—it can withstand extreme temperatures up to 550°F (287°C), making it ideal for engine blocks, exhaust manifolds, and high-heat machinery.

Key Features

  • Professional Capacity: Large 10 oz kit provides ample material for big jobs or frequent shop use.
  • Superior Strength: Delivers a massive 5020 PSI tensile strength for structural integrity.
  • High Heat Resistance: Withstands temperatures up to 550°F, perfect for engine and industrial applications.
  • Machinable Finish: Cures to a hard state that can be drilled, tapped, sanded, filed, and painted.
  • Chemical Resistance: Impervious to water, petroleum, acid, and other harsh shop fluids.
  • Versatile Bonding: Adheres permanently to metal, plastic, wood, concrete, ceramic, fiberglass, and tile.

What's Included

  • (1) 5 oz. Tube of Steel Reinforced Epoxy Resin
  • (1) 5 oz. Tube of Hardener

Pro-Tip: The strength of the bond is directly related to surface preparation. Smooth surfaces can prevent the epoxy from gripping effectively. Always clean the repair area with a detergent or degreaser to remove oil, and then roughen the surface with coarse sandpaper or a file. This creates a "mechanical lock" that ensures the J-B Weld holds its full 5020 PSI capacity.

Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.

Quality shoe but with a slight squeak.
Size: 10 Wide, Color: Burgundy Polished Full Grain
Nice shoes with the classic Penny Loafer design. Fit was better than another brand I tried. Only reason not 5 starts is disappointment due to a slight squeak at times when walking.

Exact item ordered, quick delivery
Size: 9.5, Color: Black Polished Full Grain
I ordered these black Cole Haan penny loafers for casual wear with jeans, khakies, and even business casual with slacks and a jacket. They've always worked perfectly for these uses. The Cole Haan version is the most versatile and still meets my sophisticated look criteria. I wear a 9 1/2 M with almost all other shoes. I have found Cole Haan to run slightly wider and slightly shorter. This fit will work with thin and no socks and a little loose in width. . I'd likely order a 10 N next time. I tend to forget this but it runs consistent with me for Cole Haan. 5 stars for the shoe and service. My bad on the slightly off fit.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.
