I have water that stands in my garage and I needed to carve a slight trough to allow water to drain on one side. I was skeptical that this would last the 3 feet I needed to so starting at a slight angle and ending 3/4" deep and look good. It did the job and barely wore on the metal. This will do the job and then some.
