I decided to refinish our marble island, which is 9' x 11', so it is no small task. I initially bought 5" diamond discs for an angle grinder, and needless to say, I left the island looking much worse than when I started, not to mention freaking my wife out. I found the Zoom pads online and could not be happier. The Zoom pads were easy to use, and the island is like a mirror without a single swirl mark.
Thanks again!
