My encounter with JB-Weld at Tractor Supply was an itch I had to scratch. I bought two types of J-B Weld and brought them into the Popular Mechanics shop in an attempt to find out, just how tough this repair material really is.

While J-B Weld Original epoxy dries to a dark grey color, [10] J-B Weld's ClearWeld epoxy dries clear. [11] Although its bond is not quite as strong as the Original's (3900 psi vs. 5020 psi), [12] ClearWeld is often preferred when appearance is an important consideration. [13] J-B Kwik epoxy [ edit ] I may be kidding about that, but I’m not kidding about the curiosity that this material has occasioned. Go online. People repair everything under the sun with this stuff. Most of them are small fixes to things on cars, signage, gizmos. Some of these repairs look kind of janky and might have been better executed with welding, bolts, or screws. But who am I to say? The owners seem to be happy with their results.Me and the car at the “2002: ICON” exhibit at the BMW CCA Foundation Museum in Greer, South Carolina.

Sam Bonham, at the time running a machine shop, discovered a way to create what he called a "tougher than steel" epoxy. [3] In 1968, Sam's future wife Mary persuaded him to sell his invention and he founded the J-B Weld Company. Sam died suddenly in 1989. He had commented before his death, "My life's dream is for J-B Weld to be all the way around the world, and for me to see an 18-wheeler load out of here with nothing but J-B Weld." [3] Within a year of his death, Mary had opened a European hub in London, internationalizing the J-B Weld Company and the distribution of the product. [3]

Even though it’s still not leaking, I don’t really consider this a permanent or semi-permanent repair. However, I am continuing to drive the car, maximizing its use until the snow moves into New England. At that time, I’ll pull the head and probably try to find a replacement. I made it 230 miles to Harmony, Pennsylvania, by nightfall, and I pounded out the remaining 620 miles to Boston the following day without incident.

You’ll get your best results with J-B Weld by applying it to a clean, roughened surface. Roughness (within reason) counts for a lot. First, it increases the bond surface area. When seen under magnification, a roughened surface has more area compared to a smooth one. You can picture this pretty easily if you consider, say, the surface of the moon versus the surface of a marble the size of the moon. Although both have theoretically the same surface area, the irregularities on the moon’s surface would provide increased surface to which to apply adhesive. Then, the 2002tii was accepted into an exhibit in the BMW Car Club Foundation’s museum in Greer, South Carolina, that commemorated the 50th anniversary of the BMW 2002. In February 2018, I prepared to take the car to the museum.This article relies excessively on references to primary sources.
