What I currently do is use a 175 with a Dirt Napper brush then go back over it with a Bonnet pad. If it needs it , I'll use my VonSchrader LMX first and then go back over it with a Bonnet pad. It takes longer however , it seems to give me better results. I am thinking about buying a OP machine but have not pulled the trigger yet.
