Polishing bare metal to a mirror shine on a rotary powered tool:

1) Rough polish first with a very fine abrasive rubber wheel.

2) Final polish with tripoli buffing compound on a chamois wheel.

Polishing acrylic on a rotary powered tool:

1) Rough polish with coarse pumice on a wet cloth wheel.

2) Refinement polish with fine pumice on a wet cloth wheel.

3) Final polish with Acryluster buffing compound on a dry cloth wheel.

When polishing acrylic, one has to use a low-speed setting on the rotary powered tool to prevent melting the acrylic!

HTH.

You can probably do it by hand... It'll take much longer to get good results though.
