How do you harden J-B Weld faster?
Either use JB Quik as others mentioned or mix the JB weld & let it start to settup before applying to the area you want to patch. It's an epoxy, so should cure faster with heat. Another trick is to embed a piece of window screen in the putty to hold it until it sets up.

Is JB welding strong?
General Principles: Although JB WELD makes an excellent filler---and can even be used to cast small parts, it is not remotely as strong as real metal used this way. Whenever possible, use JB WELD as an adhesive---a very thin layer of JB WELD holding two pieces of metal together.
Is JB weld permanent?
Also, is JB Weld permanent? J-B Weld is The Original Cold Weld two-part epoxy system that provides strong, lasting repairs to metal and multiple surfaces.

Can JB weld be sanded?
Furthermore, can JB Weld be sanded? For the best bond, surfaces should be roughened (or scratched) with fine or coarse sandpaper. When fully cured, J-B Weld can be drilled, formed, ground, tapped, machined, sanded, and painted.
How to repair a sanded surface?

History
The company had its beginnings in 1969 in Sulphur Springs, Texas. Sam Bonham, at the time running a machine shop, discovered a way to create what he called a "tougher than steel" epoxy. 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.
Products
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.
J-B Weld epoxy
J-B Weld is a two-part epoxy adhesive (or filler) that can withstand high-temperature environments. J-B Weld can be used to bond surfaces made from metal, porcelain, ceramic, glass, marble, PVC, ABS, concrete, fiberglass, wood, fabric, or paper. Alcohol should be avoided when cleaning surfaces, as it can degrade the bond.
