stovens,

I have used it, and so far, it seems to be working although when it dries it is so hard it can be a little brittle, so I would not put it on Door edges or where something can hit it (it can chip)-there seems to be a lot of people who don't like it out there. They say you can drill and tap it (and I believe that).

The only thing that I have wondered is if it's so hard/brittle that when some type of flex happens will it separate from the parent Metal-hasn't happened to me, however there are also people out there that absolutely love the stuff-
