This stuff has come in really handy for my husband on many occasions!  I should point out to people who might be confused about it's name, it doesn't actually "weld" metal.  When you weld metal, it is heated to a high enough temperature to actually melt the metal and a filler metal is simultaneously melted into the pool of molten metal.  This product is a 2 part epoxy that when mixed together at a 1:1 ratio hardens on the surface of the part that you are repairing.  With that being said, I still think that it's a good product.
