WORKS GREAT, WONDERFULL SHINE.  JUST KEEP CLEAN WITH SPUR TOOL.  I WASHED MINE WITH DISH SOAP AND MY FINGER FOR 4 MIN., LET IT AIR DRY OVERNIGHT .LOOKS BRAND NEW. THE ONLY BUFF CLOSE TO THIS ONE IS EITHER 3M OR MILWAUKEE.  BEEN BUFFING WITH WOOL SINCE 1978, PREFER IT . I DO HAVE FOAM PADS WITH MY A.C. DELCO 3INCH 3000 RPM BUFFER AND IT WORKS GREAT TOO.
