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. J-B Weld can be used to bond surfaces made from metal, porcelain, ceramic, glass, marble, PVC, ABS, concrete, fiberglass, wood, fabric, or paper. [7] [8] Alcohol should be avoided when cleaning surfaces, as it can degrade the bond. [9] 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. 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.

The J-B Weld Company's original product line focused on a small number of products: J-B Weld (original 2-tube epoxy), J-B Kwik (4-hour epoxy), J-B Stik ( epoxy putty), Waterweld (underwater adhesive/filler), and a few others. [4] And, regarding my BMW 2002tii, if the J-B Weld patch fails and I can’t find a replacement cylinder head, I can always, you know, just LS1 it.

Also, adding reinforcement can increase the strength of the joint. Bonding additional pieces of wood or metal over an epoxied joint can mechanically stiffen the joint and help it to better withstand the variety of forces that act on it.

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 ]
