Metal polishes are specifically excluded from this heading and classified separately. A coachwork preparation is designed to treat painted or lacquered vehicle surfaces — restoring gloss, filling micro-scratches, or providing a protective layer over paint. A metal polish, by contrast, is formulated to clean, brighten, or remove oxidation from bare metal surfaces. Products marketed for chrome trim or bare aluminum wheels would typically fall under the metal polish heading rather than here.

Generally yes, if they are formulated as cream or paste preparations for coachwork and their primary function is to restore or protect painted vehicle surfaces. However, if the abrasive content is so high that the product's essential character is that of a scouring or abrasive preparation rather than a polish, classification under the scouring preparations heading may be more appropriate. The product's formulation, marketed use, and abrasive concentration are all relevant factors.
