Outstanding product, but never in stock!
Great all purpose, fixing product, steel epoxy, that adhere to many surfaces. The only better product is their industrial strength, which dries and cures faster. Walmart never seems to have this size in stock so it has to be shipped. That is frustrating.

Still As Great As Ever
I have been using JB Weld for several years and found they have maintained product consistency and high quality. I had never seen the large size in my local suppliers and was glad to obtain this quantity. JB Weld is my duct tape of glue products.
