My 2004 Genesis Gold B lid had some scratches.  I think I made a mistake by using a scotch brite pad.  I did remove the scratches,  but this produced a deeper more pronouced grain in the suface.  Any suggestions to get back the more satin-lie factory finish?  Thought about wetsanding using 600-800 grit sandpaper, but would appreciate any tips before I start.  Thanks in advance.  Paul
