Shoot with a longish T/S lens shifted upward, so the camera sensor is still parallel with the bright surface but "below" it. Now place a white or greyish card above the camera, so through the viewfinder you see the reflection of the card in the surface of the shiny subject. With a paint can spray some nice, fuzzy, snake-like patterns on the card, to be seen well out of focus in the surface of the shiny object. Think ripply reflections. You need a wide f-stop to keep the card out of focus. Looks really cool, keeps the shiny surface from being blank. Used to do this with a 4x5 back in the day.
Without a tilt/shift lens you could just tape a card around the camera lens, try to find a position where the lens opening is not visible or at least not obvious as a reflection. Or with the "above the camera" card setup, shoot at an angle then straighten it out in PS, a long lens would work best.
