Polishing over a ceramic coating can have a few consequences, depending on the type of polish used. For instance, some polishes are abrasive and can damage the coating, while others may not be abrasive enough to do any harm.
Abrasive Polishes
Abrasive polishes are designed to remove old layers of wax and other contaminants from the paint. When used on a ceramic coating, they can strip away the protective layer, leaving your car with nothing but the exposed clear coat. This can cause the paint to become dull and lifeless, and it may even start to flake off.
Non-Abrasive Polishes
Non-abrasive polishes are designed to enhance the shine of the paint without damaging the coating. However, they can still strip away the protective layer if they are used too often or with too much pressure. This can leave your car with a dull, lifeless finish and may even cause the paint to flake off.
The Best Option
The best option for polishing over a ceramic coating is to use a polish specifically designed for ceramic coatings. These polishes are formulated to be gentle enough to not damage the coating, while still providing enough abrasive action to remove old layers of wax and other contaminants.
