«Miss Detailer» polishes cars and running a successful business

Are there different polishes for machine and hand application?

A lot of the better and more refined hand polishes can also be used with a machine. However, some polishes are designed specifically to be used with a machine only. The principle behind this is that the action of the machine breaks down the abrasives into finer and finer particles. As such, they would not be suitable for hand polishing.
