Paint care & correction

Abrasive

Abrasive describes the mechanical cutting action of a product or material. In vehicle care, a polish or pad removes paint defects such as scratches, swirls or oxidation through controlled material removal. Abrasiveness is a central factor in paint correction.

Abrasive grain

An abrasive grain is an individual cutting particle in a polish or pad. Its size, hardness and structure determine the cutting performance and finish. High-quality polishes use consistent, defined grains for precise results.
