The M1 polish is especially suitable for removing scratches from chromed plastic surfaces. This polishing paste contains a special alpha-aluminum with a minimum of abrasive but a maximum polishing effect. The surface is immediately protected during polishing.
Compared to the regular Autosol Metal Polish, this M1 polishing paste contains a minimum of non-abrasive abrasive. When using the normal Autosol Metal Polish, surface scratches on the synthetic chrome would be removed, but the painted chrome could also be sanded off.
