J-B Weld Adhesives and Sealants - 'The Original Cold Weld' two part epoxies are effective even in the harshest environments J-B Weld is known as 'The Original Cold Weld' and was developed as an alternative to traditional torch welding which is time consuming, expensive and requires a high level of skill to execute properly. J-B Weld two-part epoxies are designed to be extremely effective even in the harshest environments. Because they use a 2-part epoxy system, they utilise reactive chemistry to create the strongest bond possible. All J-B Weld epoxy products are based on the same chemistry, making them the best choice for any project you need to tackle. J-B Weld is a name synonymous in most garages and workshops thanks to its long-standing reputation in the automotive industry since its humble beginnings in a Texan truck servicing garage in 1969. Since their epoxy products dry 'tougher than steel', their use is limited only to your imagination. J-B Weld is great to use in the garage on any of your project cars, however it is just as well suited to various applications around the home for anything in need of some TLC. A handy trick for those who drive their cars to within an inch of their life is to keep some J-B Weld handy in the car. Split your fuel tank on a rock whilst 4-wheel driving or noticed a crack in your subframe or control arm whilst thrashing your beast on the race-track? J-B Weld can offer a strong bond to get you home when replacement parts are not immediately available.
