Unfortunately, I realized that on brushed surfaces, the use turned out to be extremely complicated. The order means that soaked cotton was indeed very easy, allowing the treatment by a soft cloth but very labor intensive. In addition to a white veil, it always came back to the banding. Repeated application was the result in order to achieve a reasonably good result.
Nevr Dull is not a material for removing scratches or even rust to achieve something more to a finish on a perfect surface (preferably chromium), which has lost its luster. A miracle cure, it is not, anyway.
