Black paint shows fine marks and residue clearly, so wash discipline matters. Loose contamination is removed before contact and clean media are used in a controlled panel sequence.

Cleaning does not fill scratches

Polish cannot “refill the spaces” in black paint. It corrects defects by refining the surface, and only after the paint has been cleaned and assessed.

Protection supports maintenance

A compatible wax, sealant or coating can make washing easier and support gloss. It does not prevent all scratches, and multi-year durability depends on the documented product, preparation and maintenance.

The correct chemistry follows the actual paint system and condition, not simply the fact that the car is a black Audi.
