Can't belive you only used 1 machine to polish the entire car, I've done allot of M3'a and had to breakout 3 machines, with extensions to get into those enclosed and tight areas example. ...front grill. Rails and back bumper, my 21 wouldn't fit..also, if doing paint correction ( 2 step ) why use Glaze ? Did you not achieve at least 85% defects removed ? And used glaze to fill in ?
