Here in the desert SW anything with a solvent or resin in it is short-lived, usually 1 year or less. This is true even if it is kept in a refrigerator, but the cool does extend the shelf life quite a bit. The humidity may get as low as 5%.Secondly, can JB Weld be applied in layers? Just clean surface good, apply jb weld, wait at least 8 hrs & re-apply jb weld. Far better to apply additonal layers, if need be for build up, as soon as the first layer has “set up” to where it’s stable. One may also ask, what will JB Weld not stick to? J-B Weld will not adhere or bond well to: Any flexible rubber surface. Leather. Vinyl.Why is JB Weld so good?JB-Weld is a very strong epoxy cement. 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.
